basically bitna drinks a lot and goes insane. seul helps her but she almost slips up, the mother questions bitna which angers her so she leaves to go to a hotel. seul comes with her. then we go to the other couple where hwarin's husband finds seul on the street and follows her to the salon, suspecting that seul is actually hwarin. hwarin is working at her job and she hears about people talking about bitna. then we see flashbacks of how badly bitna treated og seul. bitna was basically mocking her and showing her friends seul locked up in that basement. she was also sleeping with a random guy in the car who found seul attractive so i think he sa's her (?). bitna also brought og seul on a trip to film while her stomach was upset so she requests to go to the hospital. this angers bitna and she threatens to tell the their mom that the husband was paying for seul's sibling's school. turns out seul had appendicitis and bitna tells her that she ruined everything
i almost felt bad for bitna because seul was drugging her but honestly she's a bad person. we didn't really see how badly she treated og seul basically letting a random man molest her

spoil us what will happen from chapter 46 up to 50 please
