Mayakashi no Ai de Mitashiteyo

An insecure college student, Mahiro Miyashita, goes through a major makeover for his university debut. Since then, he's been satisfying his need for approval through a dating app. One day, he matches with a guy named Shuu, who's handsome, interesting, clever, and even amazing in bed! However, after a thoughtless comment from Mahiro, the two clash and end up having an argument, ending with Mahiro storming out of the hotel vowing never to see Shuu again. So of course he soon finds out that not only do they go to the same university, they now have to work together in the same research lab.
