볼빨간 여동생

So Jeong came to Korea to study with the condition that she lives with her relative older brothers. She followed her mother and immigrated to the Philippines when she was young, but she's planning to stay in Korea now that she's given this opportunity. It's a bit unfortunate that relatives' house is not in Seoul, but she decided to endure until graduation. Min Woo and Sang Woo are surprised by So Jeong's appearance they see for the first time since she became an adult. Min Woo is embarrassed by So Jeong, who remembers touching her breasts when she was young. Sang Woo peeps at So Jeong while she's in a shower, and So Jeong begins to be attracted to the opposite sex.
