2 parts Ongoing Chase Sachie Goroztisa is an example of someone who finds it difficult to put herself first. Masyado siyang mabait, mapagbigay siya, at mas inaalala niya ang iba kesa ang sarili niya. She can't say no, she can't prioritize herself above something.
Fortunately, her best friend, Aarkin Nikolai Firmo, is always there to save her. Who values her, supports her, and choose her over anyone and anything.
But was it casual? He's only doing that because they're best friend, whilst she mistook all the signals.
