What ís wrong abt age gap, many vouples have age gap, if all manga require age should be similar or small gap then it would be boring. By the way it is not lolicon since she is in high school, basically in japan 16 years old can marry. The guy is mature not old, so leave the manga if you dont want to read that type, we didnt force you to read why need to put harrassed words on our manga. Very narrow minded people.
