This is the worst habit Mad Snail has in all his works, he introduces the main girl early on, MC gets severe oneitis for her, she disappears for massive periods at a time(for drama), a much better girl comes along and develops a great relationship with the MC(and ultimately falls for him), MC lets the better girl hang around, shit happens, and MC eventually accepts both girls. Too bad we're just reaching the "shit happens" part of the story.
