For two days I have come to reread this chapter.
Honestly, how much are they expressive?
Their eyes, their lips, the laying of the body that tries to be relaxed or to give strength to themselves.
I really love these designs and their great ability to show us the feelings of the protagonists.
Congratulations indeed to the author

I am split in two: on the one hand I have the joy for this confession, on the other the awareness that we are approaching the moment when he will lose the person he considers irreplaceable, without an explanation, without a word <From what we know...>
I feel bad at the idea.

omg same! This moment in the manga where he realizes his friend's worth, feels a little like the peak moment in this story's climax before Jian Yi will disappear.
WAIT-
Didn't they just finish taking exams??? As in "Final exams" in their middle school??? That means that they'll be progressing to high school.
Jian Yi disappeared the second day of high school...
Oh no. We're getting closer to that date...(⊙…⊙ )

It is exactly like Kaleidocat explained to you.
Some time ago I wrote a post to explain the same thing to another girl. I'll copy it below. Sorry for my english not very good
"Most of what you see is THE PAST, with them in middle school, in tracksuits.
The scenes in THE PRESENT < Where Zhan Zheng Xi is a College student > are very few :
-the first chapters until the very long flashback <here on Mangago starts from Ch 51>
-those of this Christmas <Ch 224 Where we discover that even Mo and He Tian had separated, who knows for how much, and they are seen again for the first time>
-and very few others in the middle, like those in which they roll in the snow <Here on Mangago Ch 68> and they usually correspond to special days like Christmas, New Year, Valentine's Day and so on ...
The only thing we know about what happened in the middle is that Jian Yi says - but will it then be true? - that he had disappeared because he was taken to a desert island by his father's men <Here on mangago Ch46>
Jian and Xi don't go to high school together because Jian disappears on the second day of the first year and then reappears when Xi is at Collage. In fact, Jian tries to study to recover the lost school years and go to the same college of Xi. "
I hope I helped you a bit!
This push all of them closer and closer, more tactile, physical, just before separating them for years, is making me out of my mind.
Old Xian, you play with my weak heart ç__ç
