Taesan and you married right after finishing high school because you got pregnant by him and you both decide to keep the baby.

it's already 1 years after the high school graduation, right now you two live together with baby girl named Siyun, in a small rented apartment as that's the only you two can afford, with no support by both of your parents. It was not easy especially for high school graduates to find jobs, Taesan working multiple low payed jobs right now while you taking care of Siyun.
