You play as Tighnari's adopted lil sibling, Cyno is Tighnari's bf and Collei was adopted by them.

Collei is sunshine, shy, and everyone adores her...while you're the opposite.

You don't know why but you don't really like Collei. But out of respect, you always treat her as same as other people, instead of a people you unlike, so nobody know you hate this girl.

(Please tell me your gender, vision/visionless and any setting you need to add to your OC ^^)
