The title pretty much says it all.
and I'm looking for something angsty, :3
I like it when the seme treated the uke coldly or mean, I've read, Wonderful Days, and Hitomi no Dokusenyoku

But I hope the seme took longer than that to realize his feelings.
but, either way is fine.. 😀

Kawaii Hito - Pure
Door of Elysion
From 701 Gousitsu second story
NightS third story
Ore ni Koi Shite Dousunda
Ashita mo Tanin
Soredemo, Yasashii Koi o Suru

It seems like it's usually the uke who is unsure. I kept thinking of titles, then realized I had them backwards!

Akanai Tobira
Arashi no Ato - seme doesn't want a relationship with a straight man
Empty Heart
Naisho de Alleluya
Okujou Fuukei
Uso to Kiss, sort of

This is all I can think of right now. I think I need to read more stuff, and get some things off my 'To Read' list. But that's another story.

Koujitsusei no Tobira somewhat fits, but it's not lengthy enough for the seme to take that much time figuring himself out. He's still pretty suspicious of the uke though.

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 ♥

Barairo no Hoo no Koro
J no Subete
two related series, masterpiece in my opinion, go through described timeline, it takes seme many years to... just read it, VERY angsty
and maybe Endless World also hardcore

and sth easier Hatsukoi no Atosaki

I'm not a lolicon

Thank you so much guys! 😀

I think Koi to wa Nobenai fits 🙂
