After Rebirth, My Enemy Always Calls Me Baby

[Two male protagonists + rebirth + main attack + sweet pet + rival turned loyal dog + campus + double C] [The green tea huskies of the wealthy family VS the gloomy academic masters of the poor family] ps: I won't fall in love before I'm an adult —————— The snow on New Year's Eve took away Shen Siheng's lover and also Shen Siheng. Shen Siheng closed his eyes and held Xu Yan's hand tightly. When he opened his eyes again, he never expected to go back to the summer of his sophomore year in high school. —— On the first day back, Shen Siheng couldn't wait to be glued to Xu Yan 24 hours a day. Xu Yan was sleeping on the table while he watched. Xu Yan was doing his homework and he looked at it with his chin in his hands. Xu Yan went to the back to get water, and he had to follow. Even when Xu Yan went to the toilet, he had to go with him. Xu Yan couldn't bear it anymore, so he raised his hand and gave it to him. Shen Siheng, however, acted like he was going crazy, asking if his hand hurt, and even called Xu Yan "baby". "Have you finally gone crazy reading?" Xu Yan looked at Shen Siheng with disgust and surprise. "What are you talking about, baby?" "I asked you whether you are sick!" Shen Siheng: I forgot, at this time, Xu Yan and I are still sworn enemies!!!
