itsreadingtime's manga / #high school(115)

MC is a jerk who has no redeeming qualities. It ends with him transferring and then an indefinite time jump where we’re not told what happens with them in the time in between. Do they continue to date or do they break up until later? How did they reconnect if he left? Why did he choose to leave when the reason he wanted to in the first place was because of his “unrequited love?”
