Please Help Me Find This Manga

It was about this one highschooler who had a twin sister^that was better than him in like everything^. And one day he was trying on his sisters skirt for sumthing and his sisters bf- aka his crush-saw and mistook him for his gf. Yeah... then some other stuff happened. y u p . thank uuuuuu {hehe}

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.
I can't remember the name of that manga, please help me find it :3
