Koibito Kakin
This is perfection, but the second hand embarrassment is so real (especially in the first couple chapters where I'm not quite sure what was going on) Tsutumo is a neet that writes walkthoughs for otome games. After completeing one he finds out that the secret route is to fall in love with the supportive friend character and gets REALLY into it. But when a ticket comes to "meet" the real life yuzuru (cause the game was based on people who actually work at the company???) can he win the real Yuzuru's love?
Eccentric Hobby
Silly stories about school life after an otaku confesses to a normal kid turned hentai. There are many wild shenanigans. My fav couple is the sadist sensai and the ahoge sensei. They're so silly and cute
Chasing Mr. Ceo
Its fine. Otaku has a crush on his boss because his boss looks like his fav character. However, after an awkward company trip together he can't stop thinking about him and wants to get another job. So he interviews at another company with a man who is friends with his boss but shows interest in the otaku and so now he's got like these two men after him for some reason
Pink To Mameshiba
New sensei Mikashiba is an otaku idol fan. But apparently the clerk he preorders his idol merch from is also one of his students. To keep his reputation in tact, he agrees to become Kurokawa's dog (ie do what his says, mostly not in a sexual manner). They actually have a pretty cute relationship
