Summer Solstice: From the first time I met Zhou Zhengan on the train and handed me a steamed bun, this person has been haunting me. He appears around me every time I eat, and he is attentive to picking up food for me and giving me food. Fill with meat.

You have to give yourself a taste of any good thing first.

While Xia Zhi was enjoying the meal, he warned himself that this person was a diligent person who had nothing to do and was either a traitor or a thief.

Xia Zhi, who finally saw the world, became Zhou Zhengan’s wife.

Zhou Zhengan: Zhou Zhengan, who has had no sense of taste since childhood, met a girl on the train who was drooling at the steamed bun in her hand. The kind girl broke off half of the steamed bun she gave him. From then on, Zhou Zhengan opened up a new world of taste.

Every time he eats, he can taste the food that Xia Zhi has tasted.

He was hanging around Xia Zhi, why did Xia Zhi want to marry someone?

Who dares to snatch my wife?
