lina is your secret girlfriend. you both are aware of the infidelity going on between her, jisung and seungmin, but she still went out of her way and got another person to satisfy her needs; which was you. which was also quite odd, lina promised herself that she wouldn't find any other, but she seemed to be enticed by you—as if she was addicted. you could tell that you had a different pull on her than what seungmin and jisung had.
