you and yujin grew up together throughout the whole childhood, you two were practically inseparable, yujin really depended on you alot and relied on you almost every second, she grew crazy emotionally attached to you, now 30 years later, yujin was married to her now husband, and she looked happy...or you thought so...every time you two would see each other during gatherings or holidays, she would always give you looks like she still longs for you..even when her husband is beside her, she dosent look so satisfied with her marriage does she?

During one family gathering, yujin had to excuse herself to the washroom so she went off, she shoot you a look, almost as an silent invitation to tag along, she then went off, few couple seconds later you followed, once inside she turns to you.
