From Fujoshi Bitches:
“Tomorrow, I’ll put a curse on my father…”
Right after reuniting with his father, from whom he’d been separated when he was a kid, Ryou suddenly traveled back in time 22 years, during the peak of the bubble economy of the Showa era!
There, he met his father, Konomi, who was 3 years younger than he was…!
Living in an unknown environment with the uneasiness of wanting to go back to his own time, Ryou was anxious. But being comforted by the pure-hearted Konomi, his feelings gradually started to change… The first volume of Ike Reibun’s loved original work!

Transgressive but really moving

I read this on a whim because the time travel element intrigued me. I didn't expect to almost cry! That doesn't happen often at all for me. My heart ached for these two. Konomi was so very sweet as a boy that I couldn't take his adorableness, and beautiful as a man; while Ryo was so earnest and tender in his love for Konomi. Yes, this story contains real incest, not the fake "we're relatives but not by blood" incest, but it was really well done in spite of it being biological father and son. It wasn't creepy because it was the only rational choice given the entire situation. It's a first love story like no other, and Ike Sensei made me believe that their love wasn't wrong, which I believe is a testament to her ability as a writer, especially since incest can be cheaply exploited for shock value. She made her characters actually mentally struggle with it, so there was excellent tension throughout, especially volume two.

It was just really great...highly recommended. And thankfully this work was nicely translated by FB.

Omg! I don’t support incest, but this one got me real good. It’s sad that a son and father are twisted and fated to be intimate together. But at the end, they chose to out of natural and emotional love rather than sexual way, which is something I get. And it’s rare and bizarre for middle aged people like Kokomi to keep their youthful faces.

I don't know why, but I kept putting off reading this manga, and boy was that a mistake. It's actually a masterpiece. Although the plot is kind of twisted (I'm talking about the time traveling, them being father and son didn't bother me at all), it is well told and well paced. I was dreading from it having "yaoi hands" a bit, but it's cool because this manga is totally AMAZING! Read it.

Incest makes me squirm, especially parent-child incest, I honestly think I'd like guro better. Also, to anyone comparing homosexual relationships to incest...please just go and educate yourself or just maybe shut your disgusting, harmful thoughts inside your head thanks.

I don't know where to start.
The things that I wanted to say are most probably mentioned by these long reviewed comments 😂 the incest disgust me, but how the mangaka delivered their emotions was just too beautiful. I want to give it a higher rating, but the incest part is just too much for me lol.

To be honest I don't even know what to say. I am an avid reader of incest stories because of their usual angsty plots and I've read others that are way worse than this, but there is something in this manga that I can't stomach at all. As I was reading it, I felt like barfing (not kidding) but at the same time, I couldn't really stop reading it. There are far more way crazier characters I've read in the past but the characters a innocently twisted I don't even know what to call them. The plot really is not that amazing but I just couldn't help myself from finishing this manga. I'll give this an 8/10. If only the story sunk deeper though I myself wouldn't know how to continue it. I guess it didn't really give an impression and if not for it being incest it would be forgettable. Anyways, I do recommend this for the people who just want to experience a "What the f**ck" trance.

I had written my entire review without even mentioning the incest. That’s because I don’t really care for it or about it. First of all, that’s just a concept created by society. If you’re not able to conceive (as two guys, for example), it doesn’t really matter if you’re related or not. You, as yaoi readers, you be more open-minded. Furthermore, if you do have a problem with incest, you haven’t read enough yaoi. I’ve been a yaoi reader for almost 15 years and I’m young, so there is really nothing I haven’t seen yet. If there is something you are getting surprised about, that just means you haven’t gotten deep enough into the genre.

Now back to what matters. I've started reading this manga because someone said it was the best portrait of yaoi incest they’d ever seen. While I can't agree with that statement, as I've read better ones with that theme, this is one of those rare, deep, intense stories that you should stop everything to read. But beware! After reading the first volume (roughly 130 pages), I was thoroughly disappointed. The first volume is a complete cliché. Nothing special, except the time-travel (which is never, at any point of the manga, explained). Though I like sci-fi, since this wasn't a story about that, I think it's better off that they did not explain the time-travel. However, the story was quite boring. Being transported to the past, having to make your own money because you have none of that time's currency, having to adapt...none of that was original for me. Also, the way Ryou and Konomi fall in love in the first place wasn't even surprising. Thunder, hugging and leading to kisses and sex, in two weeks? Boooring. And Ryou didn't even hesitate to kiss his father. However, I do think that can be overlooked as Ryou’s feelings might be a little more interesting. Even though that was not put out there at any point, I think part of the reason he fell in love with Konomi was because he wanted to feel close to his father in the first place.
With that being said, in the second volume, I understood. I finally understood why this manga is popular. The way the volume begins is already heart-wrenching and it only gets better from there. They struggle with their feelings the whole volume, like it should be always, in every single manga. After all, it's not a matter to be taken lightly. While I didn't shed a single tear, and I cry with just about anything, I do think the pace was just right: slow and difficult. One of my favorite things about this manga is the sexual tension. Since they are holding their feelings back so much, every time they see each other, it's so deliciously angsty. I also really like how there are no stereotypical attempts at making this manga like any other yaoi. No situations where a girl comes in and the other character is jealous and screaming (even if the extra is about that, it's just a cute, short story, nothing dramatic), no sleeping around until they realize their feelings for another...nothing. This is purely a story about feelings, and years and years go by before it can be resolved.
The artwork is quite good, though I don't really love Konomi's face. As for their personalities, I love Ryou. He's not a particularly outstanding seme, just hot, a bit sex driven, nice, a little but pushy and stubborn. Konomi is not my type of uke at all, as he's so whiny and annoying. I can't stand him when he's 14/15. When he's older, though, it seems like he gets a little bit better. There is actually a great point in this. It is very clear how Konomi has a different maturity level than Ryou, both when he is younger and when he is older than him. Past-Konomi is still a kid, scared and exploring the world. Adult-Konomi is actually more reasonable and, unlike Ryou, who acts on his emotions, he is very realistic and it shows that he is an adult and not an adolescent / a young adult.
I don't really enjoy how they cry so much in this manga too. I understand it is a hard thing to go through, but it seems like they are ALWAYS crying. The flow of their thoughts, on the other hand, is really good and well-constructed, and frankly, quite different from everything else I've ever read.
I did like the sex scenes. It's not always the seme that has to attack and give the uke pleasure - it works both ways. And I've seen mutual affection in the sex scenes in this manga. I do think the way they finally end up together is weaker and quicker (the scene on its own) than I expected, but the dialogue is absolutely beautiful and astonishing.
To summarize, this manga has both positive and negative points. I cannot give it a 10, as a lot of people have, because it is NOT perfect. But I will give it a high rating because that's what it deserves.
