In episode 1, Xiaozhuang, Kang Hesi are roommates and three supporting roles. The cute Xiaozhuang is a sophomore, and he thinks he is a world-beater handsome guy. After class, Xiaozhuang works in a coffee shop and is the vice president of the food club. Kang is known as the king of ideas, especially in picking up girls. His methods make people admire him. He always takes two friends to meet his sisters from different schools, which makes them laugh at dinner and makes his brothers admire him more. As an overseas Chinese in Korea, thinking without learning without skill, his special specialty is to make people mentally weak in one minute. Under Kang's guidance, Alice pretended that her leg was broken and went to the hot dance club to watch the hot girls dance in plaster. After watching it, I also commented on who danced the worst on the internet, and the girls from the hot dance club gave me a lesson. Xiaozhuang's idea that he is a super handsome boy was laughed at by two friends. He tried his best to make him understand the fact that he is just an ordinary person. Kang gave Xiaozhuang a difficult problem and asked him to ask Cindy, the school flower, to determine whether he was a handsome boy who met Cindy's aesthetic standards. Cindy, the school flower, loves to issue "good man cards" because she always says to suitors, "You are a good man, but you are not suitable for me." Unfortunately, she was in a bad mood this time. Xiaozhuang didn't get a good friend card, but Cindy scolded her, "You are so ugly." Xiaozhuang, who won the "ugly card", was laughed at by his classmates. Cindy has a crush on her brother-in-law who is a veterinarian. Under the influence of her brother-in-law, she is very concerned about stray dogs in the park. My sister left for some reason, and my brother-in-law missed her cooking. Cindy knew about it and joined the food club. She met Xiaozhuang here and divided them into a group. Xiaozhuang's good temper attracted Cindy, and they became good friends who talked about everything. (Come to Baidu Encyclopedia)
