Overrated

The artist is good but the plot is shit

Like after chapter 2 i couldnt take this seriously. Like the gf of a friend is trying so hard to make mc jelous cause she secretly loves him, but whenever he accepts her advances, she pussies out. Only when a rival appears does she stop playing her shitty tricks on him however he chooses not to do shit with her.

Honestly hard to like. If i was mc, i would tell the gf lady that if you want to be with me, break up with ur bf, i refuse to date people who are already in a relationship

Red flags all around

Seems the girlfriend isn't the only one waving red flags. Turns out his friend might also have his own red flags the MC should look out for.

It's looking more and more likely the friend is

just dating his GF out of a fucked up sense of rivalry with the MC, with whom he appears to have a severe inferiority complex with.

Regarding this

inferiority complex: if the friend noticed early on the girl liked the MC, that would mean to him he is "losing" to the MC if they started going out, so it's likely he asked her out before MC could realize her feelings. The girl, being close to them both and seeing MC apparently uninterested, starts dating the friend. Either to get him jealous, or she's taking her chances with someone she thought actually liked her.

I wouldn't be surprised if it turns out later

the friend also took or tried to take "all her firsts" early in their relationship not because he's attracted to her but just to have more and more things that he's "won" over the MC. Might explain why she grew cold to her "boyfriend", when she realized that he didn't really love her and was just using her to scratch his fucked up rivalry itch. Now she's coming on to the MC, because 1) she liked him originally and maybe 2) to get back at her "boyfriend" for pulling this shit on them.

I wouldn't trust them both. Better run. Just. Yikes.

Generic ch1-4 *Edited*

Rating: 5.0 / 10.0

Not the worst but looking like the ol "I dated the friend cause I wanted to make you jealous and for you to want me more" trope. So far not really much characterisation and not much info about the triangle thats happening. 5/10 as a result.
Also the name of the series is kinda off? Why Someones Girlfriend when it's his best friends?

to ch4 edit

So yeah it's really looking like it's the old "I dated the friend cause I wanted to make you jealous and for you to want me more" trope and that just makes the character motivations/actions make the least sense.
If MC has always had a crush on her then why did she date the best Friend if she wanted to be with MC? Why continue to be with best friend if the MC is showing interest now? This feels like NTR for NTR's sake and not for good writing reasons. This series is starting to fall apart already as a result and I'm actively not rooting for any of the characters as the best friend also seems to be a douche or in the least not what he really seems.

Mangakatana's rage

From Manga Balls Deep!

*Honestly, this is one of the worst endings to a series I’ve seen in a long time. The writer, Nikumaru, completely gaslit us throughout the entire story. He makes it clear that Minase is sick, yet never reveals what her illness actually is. She even goes through surgery, but we still have no idea what she’s suffering from. Then, just when things finally progress and she and Riku become intimate, instead of showing us what happens next, we get a lazy 2-year timeskip that tells us absolutely nothing.

Riku’s living a good life now, he’s in college, and that’s fine, but it still leaves huge holes in the story. What happened to Minase? How did she just disappear without a trace? He was literally just at her apartment before she vanished. Why didn’t he go back? None of it makes sense.

To me, it’s a despicable ending. And if the writer has to release an epilogue just to fill in the missing pieces, then what was the point of ending the series like this in the first place? Mangaka really need to stop using “reader interpretation” as an excuse for incomplete storytelling. All it does is make people lose faith in the work they created.

You can agree or disagree, but in my opinion, this ending was not only disappointing, it was hollow. The series barely had any room to grow, and it feels like Nikumaru just stalled until he ran out of ideas. We got more character development out of Umimi and Yoko than we ever did from Minase. If this was meant to be some incentive to buy the next volume, I’m sorry, but that's just a waste of money*

Piece of shit ending

by deganes

Rating: 1.0 / 10.0

There is no clarity about Shizuku's condition, whether she is cured, what her illness is, whether she started a serious relationship with Takt, or whether she died.

The ending is just a completely meaningless timeskip, the audience would rather see what happens to Shizuku, not Umimi or anything else. Damn.

A long, futile wait, a cowardly author who doesn't even dare to create a clear ending. And many of us are disappointed and won't even look back to see your other work.

The author just escapes by using the words "let the reader imagine the ending for themselves"

Damn, the biggest disappointment of the manga that has been waiting for the ending.

If it does end badly, and Shizuku marries Takt, then just write why not. Or if Shizuku dies or whatever, at least it seems clear what her fate is.

Others are too harsh with this

by dangerdude

Rating: 9.0 / 10.0

One thing I did confirm after going through all the reviews - never judge a manga by others' reviews. I personally am absolutely loving this manga. Yes true, some strange stuff is indeed brewing but the fact is that the MC is getting all the graces. The female lead is indeed going out with the best friend but it gives off the feeling of being obligatory. The reason I don't give this a 10 is because I still don't know how this is gonna turn out. Well, let's see. I am having an absolute blast as of now.

Highly recommended!
