So it has been a long time since I have been here, but ah here am I again and still want to read yaoi even now when I am 19... 🤣 Is it fate?

Anyway I would like to read a manga where the seme falls for the uke first and maybe tries to hide his feelings (if a manga like that exist?) I guess something close to it would be fine, but just as long as the seme falls for the uke first and it is a cute story then I am happy 😃

All of the below comply with the major part of your request, but most of them don't fit the "tries to hide his feelings" bit, and some of them aren't all that cute, just normal. Nothing nasty, though, since I don't like that kind of stuff:

Ai Koso Subete (KINOSHITA Keiko)
Don't Cry Baby
All the stories in Retsujou
Himegoto Asobi
Kuchizuke wa Uso no Aji
Tsukiatte Agete mo Ii n Dakara ne
Aruhi Hyouhenshita Shinyu ni Kokuhakusa Remashita
Akai Ito no Shikkou Yuuyo
Dounimo Nannai Soushi Souai

There's a category for this, too.
