Seo’s confession will be a lot sooner than you think

It’s actually at the end of chapter 98. At first Seo considers just going off to fashion week to avoid thinking about confessing. After a night of having sex Seo skips out in the morning, leading Baek to think this as rejection which of course makes him sad but he doesn’t say anything. Baek stops at Seo’s to say he is going on a far business trip and says goodbye, but Seo thinks he is going to accept a two to three years abroad assignment, shortly after Seo finally decides to get up and run after Baek.
