They are in the end of their middle school year (15-16).
Jian Yi will disappear when he graduates to high school related to some shady business with his dad (around ch.46).
It’s hard to explain all things here but if u read it carefully generally it should be fine.
(Time if u’re extremely confused :

Hope it helps !
So I stared reading yesterday and I'm all caught up now but what did they mean with disappeared after the second day of highschool? And are they in middle school rn? ( ̄∇ ̄")
