Why people said that "why can't he just remove the errors?" Cause that's the whole point here???? I'm pretty sure that the brown haired guy didn't know how to, but literally just giving false hope to MC who's desperately needed help just for him to take advantage of. The only goal in this dude mind is "having s**" with MC. MC on the other hand already stressed beyond belief with all of those fiasco and is not exactly the bravest person out there in the first place, plus he didn't realize his own feelings and are still confused by it. 
Life is overrated
