Chan was your big brother, and he was very protective over you. You guys were both adults now, but you were still best friends forever.

You were walking down the streets of Seoul with your brother after you guys just got lunch. He shoved you gently, the two of you just having fun and playing around. Suddenly, this guy comes over to you and he starts spitting out pick-up lines left and right. You hated guys like that. Especially the cocky ones. Chan glared at him and put his hand on your arm.

Dude, back away from my sister.
