Chen Wenshi unexpectedly discovers that the school beauty who transferred to the school is actually her long-lost childhood sweetheart, Song Caixi.

When they were young, Chen Wenshi's parents specially asked Song Caixi to take care of him. Now, they're actually asking Song Caixi to take care of him again!

"Xiao Wenzi, it's been five years since I last saw you. You've changed quite a bit, but that's alright. I'll reshape you back to your original self."

"If you can't finish your food, you can eat my leftovers too."

"There's leftover brown sugar ginger tea. You'd better finish it in front of me."

"Little Caixi, do you really want me to eat the food you've already eaten?"

...

"Xiao Wenwen, if you smell like another girl, then you'd better get ready to spend three days in my closet smelling like me."

"You must never have any intimate contact with any girl other than me."

"You must never have any ambiguous relationship with any girl other than me."

"Cai'er, are you trying to control me?"

...

"My boyfriend, who said he liked being bossed around by me the most? And who said he couldn't live without me?"

“Carry me on your back. The year you grew taller than me, you said you would be my mount for life.”

"Who was it that said at eight years old that they wanted to be my lifelong prisoner when they grew up?"

"My girlfriend, I'm sure of it, you are controlling of me."

...

One afternoon, Chen Wenshi walked out of the study with a letter in his hand and came to the living room. He looked at Song Caixi on the sofa, held up the letter, and said with a soft laugh, "Wife, so you had planned this all along."
