Whaaaaaaaat? They are middle school kid? But they were school boys, werent they??

middel school is school Oo so what? i guess the r 3rd yearmiddle school so some month and the go high school

After middle school comes highschool. They are their last year of middle school...although He Tian looks like a guy from senior year...

nope ITS clearly stated before that they r now MIDDELSCHOOL

I guess He Tian's 16? Still, what kid smokes a cigar? I guess the translator should clear our doubts.

When they are on school (before the time skip) the characters are 14 or 15...
They are older (around 18) when Jian Yi comes back and Zheng Xi is in university.
And honestly, many children start smoking when they are 12 or 13 years old (maybe not most of people, but a lot of them start "trying" alcohol or cigarettes, at least at parties at that age...)

he probably thinks he looks "cool" smoking a cigar, like a mafia boss XD
And at first it shocked me too that they are so young, but some people (like 2 of every 10 boys/girls) looks older than the rest. My little brother is 12, my little sister is 11 and both of them look like if they had 14 years old. (because they are tall and outgoing)

its more likeley they r still 14/15 . i know the look mature in most closeups but if u even check last chapter in this panels like the upper http://www.mangago.zone/read-manga/19_days/bt/c161/pg-7/ they look like middle school kids from head to toe.

Sorry but they are in middle school right now. They are going to be in the same high school later on but Jian Yi disappeared without a trace on the second day. He came back 3 years later. Zheng Xi is in college and Jian Yi is still in high school.

That's quite the shock for me,, coz from where I am coming, people usually get into smoking when they are. 20ish.
