What do you mean? This is not happening in the present?
the time frame in this manhwa is so confusing, now that i've read over what i said i may be wrong!! i think this current chapter and the previous 5 chaps are total recaps of their past which is their high school days! i think the present day is chap 140??? but then the "present present day" is zhang xi in college while jian yi is continuing high school again because he disappeared for a year/2 years ??? idk if that made any sense.
Remember how at the beginning of the manga, Zhengxi asks Jian Yi to hide him from the stalker girl, and he covers him with his shirt? From that point on, it has been a flashback from when they were in high school. Everything before the stalker girl thing was from when Jian Yi returns and Zheng Xi is already in college
Are you talking about this part? http://www.mangago.zone/read-manga/19_days/bt/311118/Ch48/1/ when jian yi asks zheng xi to teach him, zheng xi said that it's been too long and jian yi said he wants to be on the same uni with zheng xi
but this is still in the past though , like jian yi doesnt tell his feelings until in the present :/
