NoSigh... Bro needs to spend more time with his actual girlfriend !!
Same way you figure out the rest of their personality, I suppose....How do you figure out a cracked screen by photos?
Aside from this story, having friendships of the opposite sex is a normal and healthy thing. You can have friends without some kind of sexual or emotional attraction, not everyone needs to be a potential partner or conquest. What is it that makes the opposite sex unable to genuinely connect on a platonic level?I really hate how manga/novel MC's lack of boundaries when it comes to relationships.
Oshio has a girlfriend and still hangs out alone with another woman and the manga don't treat like it's a problem.
