Hwan-hee (Seohyun) was Jeong Jay's (Lee Jae-yoon-I) first love and it was awkward when they met.

Hwan-hee said, "You haven't changed. You are exactly the wayI Remember You. It's been a long time".

Sang-goo (Min Seong-wook), who used to like Hwan-hee, felt jealous at the way she looked at Jay. He then said, "You're still the same goody-two-shoes aren't you? Girls liking you and all. Isn't she your type?"

Jay tried to stop him but Sang-goo wouldn't stop provoking them and Jay eventually punched him.
