A girl who is an obsessed girlfriend. Su-ah, or also called Sua, tends to be emotionless entirely. But she does blush when she’s with her boyfriend, Yu-Han. But that’s it. Nothing else. Just blushing. She also tends to be stoic and also intelligent. She can be quite protective as well. She tends to hug her boyfriend from behind. Despite this, she’s a bit sweet and sorta kind with her boyfriend.
