[Two male protagonists, senior, age difference, short story, air-conditioning decorator with cheerful personality and excellent cooking skills VS super social fearful novelist] The first time he saw Yin Chengyi, Bai Yu thought he was a bit stupid and strange. He was wrapped up tightly and dragged with several large suitcases. He stretched his legs to block the elevator door and then pushed the suitcases into the elevator. But who knew he was so kind? So he helped others push the suitcase in. Unexpectedly, he didn't even get a thank you. He was such a rude and stupid person. Then after returning home at night, he saw this rude and stupid weirdo again. Oh, it turned out that he was his new roommate. Later, Bai Yu just felt sorry for this stupid weirdo. He was not strange at all. He was very cute and nice. It's not that he's rude, he's just too timid.
