hi just read (skimmed) over chap 29 heres the gist of whats happening
Spoiler!
(yoil = mc | yoonwon = ml) all in order ↓ - yoil sees yoonwons drawing of him, is a little embarrased - class ends, everyone leaves but they stay behind - yoonwon sits on some desks and makes yoil sit on his lap - yoonwon teases yoil a bit, kisses him, touches his bu** and stuff - they get heated and do it on the school desks (its like one panel, not really detailed) - timeskip - yoil is at the subway - he gets a call from yoonwon then hears some girls fawning about a trainee idol called kang heejae - yoil starts getting anxious then sees a billboard of kang heejae while running - then a few seconds later while he's in front of the billboard heejae comes up behind him and taps his shoulder then the chapter ends
