The story is overall pretty good, but the ML is very stalker-y. I wouldn't say that's a bad thing if they properly explained how fucked up and weird it is, but they just brush it off. The guy shows up in front of his house, knows his private number, knows everything about his life prior to even speaking to him for the first time. And it never creeped out the Professor at all... In fact, in the later chapters, they brush it off like it's a silly habit. Stalkers aren't attractive, you know...
