Hello. <3 I'm looking for a BL manga I've read before, but I can't remember the title. >.<
Two guys had a relationship in the past, but the seme dumped the uke cruelly. The manga starts when they run into each other years later and the uke plans to get revenge by making the seme fall in love and dumping him this time (except he's still in love with the seme, has trusting issues, etc.).

I'm sorry if it's rather vague, I hope your memory is better than mine.
I'm looking for a specific manga, but I'd love to read other ones with a similar plot, so please let me know if you have any recommendations. :3

I would recommend Kono Ore ga Omae Nanka Suki na Wakenai, if you have not read it. 😃

Intense Rain and Puchitto Hajiketa, ex-lovers reconnecting.

Thank you so much for the suggestions, I'll definitely check them out. 😉
I love Hatsukoi no Atosaki, which has a similar storyline, but I still can't remember the title of the manga I'm looking for, so frustrating. >_<

I don't know about the title you're asking for but since you ask for more recommendations on that line, maybe Shiranai Kao? (just the first 3 chapters). It's by Hidaka Shoko so maybe you've heard of it 🙄

It's the Art of Time, it's the Art of Life--
Of the player and the craftsman,
Of the writer of songs, of the creator of love,
Of those who will follow, of those who led,
There's no other way in the world ahead ♥

Yeah, I can't remember much about that manga, because it's been a long time since I read it, so I guess it's hard to figure out the title. 🙁 But thank you so much for trying. <3

Oh, Shiranai Kao is on my to-read list! Since you recommend it, I may as well read it now. Thanks! 😁

Wasn't seme some kind of an architect or construction manager?
'Cause I remember something like that, too.. Although not the title.

KuroiMarimo, maybe you're talking about the first couple in Koakuma no Sanctuary? Loved this manga, by the way.

I don't remember what kind of jobs the characters did in the manga I'm looking for, it wasn't focussed on their working life.
I only remember useless things, like them having drinks together, or seme visiting unexpectedly uke's house, which happen in pretty much ALL yaoi manga so it doesn't help at all. 😔

Bump! I haven't found this manga yet, does anyone have a clue?
There may be a wedding ceremony involved (they met there?), but I could be mistaken with another manga, that's why I didn't mention it before.
