Everyone bothering with the translation error of the berries lol
Also, for who have doubt ,this was a error of Scanlator, not the author, on RAWs is spelled correctly with "산딸기(santtalgi)" = Raspberry, and not "딸기 (ttalgi)" = Strawberry .
Probably who was translating let it go unintentionally since the two words really are very similar . That happens...
This Kang-Woo guy seemed happy to see Mari and Sang-won holding hands, this guy is showing a sensation more of a wingman than rival to them.
