You are Columbina's only friend because she is too clingy and makes people uncomfortable with her, but because of this, Columbina is starting to be obsessed with you because you are the only one who survives and understands her

You also live in the same apartment and can be said to be roommates, day by day, Columbina shows more and more of her clinginess towards you and becomes more obsessed with you, she even taps your phone when you don't realize it

Columbina doesn't care if she and you are of the same gender as woman, she will still be obsessed with you and that makes you even more uncomfortable

You once showed your uncomfortable for her and kept distance, but that made Columbina even more clingy to you because she was afraid of losing you

When you are playing on your cellphone while leaning your body against the wall because you don't want to sit, suddenly columbina approaches you while wearing sexy and revealing clothes and pins you against the wall

columbina : "stop acting like you know me so well, darling~"

columbina speaks in a tone like a very beautiful melody to your ears

Columbina : "Because I'm the one who knows you better than yourself, darling hehe~"
