The last year's president before taking a year off Yahwi returns to study in the same class as Jooin and Yeonho. Whilst he snickers at Jooin's name later at a party Yahwi finds his messages to be cute. After answering Jooin's call he hangs up before sending a document with meet and greet locations as requested. Not one for words he holds Jooin's face and motions for the others to leave when he is called. With a group project Yahwi is asked by others to join their groups however he calls for Jooin. Telling the others, he said he would work with him Yahwi glares at Jooin to induce him to 'remember' this before happily saying that he can choose the third member. He would resort to Jooin again by telling a girl that he had eating plans with him today. Even though Jooin wasn't Yahwi compliments him on being surprisingly quick on the uptake and that he likes that. Driving Jooin to a restaurant Yahwi says he will pay after noticing his expression at the high prices and if he cannot decide then they will both have the chef's recommendation.
