[Older Woman-Younger Man Romance (Five-Year Age Gap) + Sweet Romance + Both Pure + School Life First, Then City Life + No Catfighting Between Women + Healing]
A big sister suddenly dropped into Jiang Che's life.
The first time they met:
Jiang Che: "Who is this person? She's so annoying!"
Lin Yu wanted to pat his head.
Jiang Che (furious): "Get lost. Don't touch my head."
Later:
Jiang Che shouted at Lin Yu, "Why isn't my big sister like everyone else's? If other people messed up their sister's room, she'd give them a beating. Why don't you? Other people's sisters are always ordering their little brothers around. Why don't you..."
Lin Yu: ...
Many years later:
Jiang Che pinned Lin Yu to the bed. "Don't lie to me, Big Sister. You like me too, don't you?"
Note: This is a slow-burn romance.
