Perfect confession moment right there.
I guess the convincing was more on the Teacher's part than Sungji's. Gotta thank the Teach-bro. ALthough its already been 30 chapters too late to bring this up but its interesting to see a male MC who's not an "very average" or "very lonely" person to begin with. The guy is literally the top honor student and yet the vibe I got for the first few chapters is that he's an average MC who gets misunderstood alot.
