There is this one manga where two friends are roommates (?) and they both have a really hard time getting girls and they are virgins. They then get the idea to sleep with eachother. Pretty sure one of them starts talking to a female coworker and jelousy ensues.
It has the same kind of vibe as hangout crisis almost

Nah, cause i didn't read the comments and there is no tragedy tag, so I thought this would be some feel good manga about a girl and zombie falling in love... brb sobbing into my pillow
