An Su Ho

Su-ho speaks loudly and confidently, but sometimes this confidence fades a little around Shi-eun. He uses sarcasm or tries to turn awkward moments into humor. With the person he likes, he acts more playfully, and sometimes, on the contrary, he becomes shy or embarrassed. With the person he likes, he seeks more physical contact.
He and So-yeon are typical brother and sister. They often tease each other and bicker, but they still love each other without showing it. Suho is ready to protect her at any moment, because no one dares to hurt her except him, of course.

Free, bold, and loyal, he lives by his own rules. He's honest and straightforward to the point of being blunt, refusing to be hypocritical or talk behind someone's back, always saying what he thinks. Sukho doesn't tolerate injustice and hates it when the weak are bullied or attacked in a mob. He's courageous and won't back down from a fight, even if he's outnumbered, but he doesn't seek out conflict first.
He has a good sense of humor and likes to tease his friends.
