@Wiinnie In a previous chapter there was another flasback panel which can be linked to the one in this chapter. We see a younger Taeha sitting at the bus stop who spotted Haesoo running in the street, her clothes all roughed up and her body covered in scratches and injuries (maybe running away from loan sharks). This supposedly was their first encounter. The fact that she took care of Taeha's injuries while being in a harsh condition herself is so sweet!
