The usual schooling in Japan (and korea) is 6 years of primary school (from the age of 7 to 12), 3 years of junior high school(from the age of 13 to 15), 3 years of senior high school (from the age of 16 to 18), and 4 years of university education(from the age of 19 to 22).
they are most likely to be 15
So they're 15 ?!
oh yes . . . ┗( T﹏T )┛
What can I say, they look older ╮(￣▽￣)╭
But I still love this manhwa (๑•ㅂ•)و✧ (even if that age a little disturbs (￣∇￣") )

does this mean that they are in middle school? (〜￣△￣)〜
