Lol, they never became official. They were "some", like MU but never actually dated seriously — like with labels. If Woojin really liked Yoojin, he would have been so affected when he saw Minhoon with her, just like how he came to know about Gayoung and Chanhee. He had a crush on Yoonjin but his feelings for her is nowhere near how he feels for Gayoung — love.
^^^^^ and when they had that call, Ga Young asked Woo Jin if he and Eugene were dating and be said “no” and she was like “better tell her soon then”
(That part hurt so much, imagine how much that must’ve hurt to tell the person you’re in love with to tell their crush they like them :/ my heart hurts for her)
Feel like gayoung deserves better than woojin. Ik woojin is nice and all i just dont feel that much love coming from woojin seems like gayoung is the only one who tries in the relationship. Also hate how woojin dated eugene so quickly whilw he had to think about dating gayoung.
