The setting of the time skip is absurd, the fact that the ML becomes so immature like a grade schooler who can't convey his feelings (there were signs of it before the time skip, but i guess his character was masked by the plot) etc makes this manga pretty unreadable that even the fact that the ML and FL finally getting their feelings across to each other doesn't help it all. So really, just stop at volume 4 or you may become like me where you get extremely angry at the author to the extent that you have to write a comment like this to vent.
