Somebody knows? It`s bothrting me for some time now. Style of art has changed a little, and when I go back I`m getting confused. Sometimes they look like they 18, and sometimes like 12.

Thats how I get it too. Jian Yi has disappeared 2 day of high schooll, so this has to be during middle school, but just wondering which year... For me it looks like final year, cause they`re kinda big for middle schoolers. But then again I look at this page: http://www.mangago.zone/read-manga/19_days/bt/310937/Ch63/1/
and they look like kids.
And after the timeskip they have to be at leat 18, cause XiXi is already university student.

umm i believe he disappeared during his junior school and came back after 2 years ( middle school) the begning of chapters was when he came back and latest chapters are flashback..i thinkk..

1 to 50th chapter; Zhan Xixi is at uni but He Tian isn't. OldXian says He Tian dissappeared second day of highschool thats why he couldnt go to the uni but he wants to go to the same as he => http://www.mangago.zone/read-manga/19_days/bt/311118/Ch48/
50 to current chapter (167th); they are in middle school. => http://www.mangago.zone/read-manga/19_days/bt/c161/pg-6/
He Tian says they should go to the same highschool so it means they are in junior high. If they were more younger he would says they should go to the same junior high as well. That's why im sure they are in junior high.
But they are growing of course cuz in this story OldXian sensei try to show us time differences and the story is not a "timeless" one. They need to grow up because we all know how they look like as adults => http://www.mangago.zone/read-manga/19_days/bt/311093/Ch6/1/
So it would be nonsense if they look like the same in junior high or they wouldnt grow up in junior high chapters. As we know now they look much older than the first junior high chapters. I mean look at this cutiepie stupid trashes=> http://www.mangago.zone/read-manga/19_days/bt/311122/Ch52/
And current chapters *nosebleed* => http://www.mangago.zone/read-manga/19_days/bt/42370ebe2b1ee93a/Ch166/pg-3/
Well as you see im bringing back the most wonderful scenes so im awesome right ( ° ʖ °)
Anyways they are probably 19 or 20 in first chapters
And they are 13 in the beggining of the junior high parts (since the junior high school in japan lasts 3 years)
And in my opinion they are at their last years in the middle school (current chapters) so they must be 14-15 yo .
And its nearly 4 a.m. so i should shut the fuck up and read another yaoi manga (sleep is for LoSErS -lol sorry I felt like im twelve again) I hope I help some people in this horrible yaoi heaven (Actually im just so bored and have lots of free time thats why i write up allll the fucking things that i though is related to the question. Just ignore me if you dont wanna cuz I am an oneesan who is really bored and drowned in anime stuff
Oh what have I done i rly neED LifE
Kamisama bless my heavydirtysOUL

When I finally realized what is going to happen my heart skipped a beat, eyes opened wide and jaw dropped. I was sitting like that for a moment, taking a delight in this feeling as I started to grin.
What a brilliant idea! So simple, so obvious, yet so surprising! I haven`t get this kind of excitement in years. This mangaka is genius!
