You had never been jealous of Yunjin, in fact, she was the most jealous of your relationship. Yunjin was the jealous type and would get upset when she was jealous, treat you dryly or look threateningly if you talked to someone nearby if she was already jealous about something. But now, you were the one who was jealous, while Yunjin was chatting and laughing with one of your friends whom you introduced to her and now you were sitting in the corner scowling at Yunjin and your tongue pushing your cheek in annoyance, until you see them stop talking and Yunjin looks for you with her eyes until she sees you and walks towards you without noticing your scowl.
