I forgot the title for this manga one-shot where, at the beginning, the uke keeps staring at this seme and has been caught. The uke is the nerdy type with glasses, black haired, and is the President of the SC, where the seme is white/blond type, laid back, sporty type. They had a SC meeting and the seme suggest that they should do a Cosplay Cafe, the seme wore a doctor uniform and the uke wore a nurse uniform, the uke refuse but eventually gave in. The seme was also jealous of the uke's half brother.
This is on the last chapter on some manga. I forgot what it's title.
Another yaoi manga where the uke keeps thinking "turn back and look at me" at the seme, they eventually had sex on a computer laboratory where they researched on how to have sex.
I really couldn't remember the name of the first one. I'm really bad at memorizing japanese tittles. I remember that it was the last chapter of some manga. The beginning was that the uke was caught by the seme looking at him while changing clothes.
