Sit, Wait, Kiss Me
Tanyi becomes gradually attracted towards the mc only to discover his human self, which was under a curse.
Saihyou to Tokeru
Everyone hates this but Rui's case was not so stupid, he had waited to love his teacher legally but refused to realise that the sensei decided to end things with him, and before he could stop anything his sensei left him... When Kazushi saved him, he couldn't suddenly move on from yearning for his sensei but always regretted being with Kazushi...until he was saved again he got over himself and loved the guy in front of him. The pacing of the character development of Rui is natural and I don't mind at all, most of the mangas written by this author don't just follow the cliche yaoi ending, it concentrates upon a particular character as a whole.
Fukujuu to Amagami
The doctor is a lucky bastard but anyways, the doctor is a hopeless furry lover who's also clueless about his loneliness and feelings while Iruma is a cute tsundere who yearns for love. Basically two idiots failing to confess properly.
Itoshi no Mirai-kun
I love innocent and sincere characters and I really adore Mirai, it's true he's not realistic and he's used as a tool so his boyfriend protects him after understanding him.
Kabe no Naka no Tenshi
