Please Help Me Find This Manga

Mangago transports us into a world where all anime/manga/manhwa/manhua characters are alive.

From what i remember its about two college students and the seme has always had a girlfriend but never stays with them long. I know that the uke wears glasses and theres another dude thats gay that realises that the uke is also gay and offers him cigarettes and then when the seme finds out he gives the back to the other guy. It turns out the seme has always loved uke boy, and when uke wants to talk to him the seme is like really adamant that its not alone together but the uke is like ‘this important shit tho’ and then sex or something idk.

Im terrible at describing this stuff but ive been searching for it for like 4 days. I dont know why but theres another one about asking the seme which fairytale he just fell out of so if you know that one too that would be great!

Thank you!!

Hi, could anyone help me find a yaoi manga? I remember it was something about a young rich man in army who was about to get married to some army douche's daughter but he was kidnapped by pirates before that, the captain fell for him & at the end the uke realized he fell for him too & rejected his fiance and ran away with the pirate captain to some island where they jumped off a cliff together & kissed under water at the very end of the manga.

Protag transmigrates as the villainesses fiance and is in love with her

So I read these a while ago and want to re-read them but I cannot for the life of me remember what they are called.
Manga 1: Male lead lives in the boarding house run by the girl's dad and I think he refers to her as a landlord. He seems goofy and wears glasses but in reality he is a famous singer in a band. I remember one chapter she goes to his hotel and when she is leaving, thinking that he rejected her, he catches up to her on the elevator and they kiss. I'm not sure if that helps, but that's all I can remember.
Manga 2: The girl reads lyrics that the male lead wrote on his desk and it makes her interested in him. I feel like the title had the word senpai in it but I'm not sure. They start dating super early in the manga and he starts liking her more and more as they date if I remember correctly. I'm trying to remember specific chapters. There is a chapter where they are having a school festival and she visits him and he is hiding in a box for his classes' haunted house and she gets in the box with him and they start kissing. That's all I can remember.
