Wild Strawberries

A cunning, ambitious little rose who climbs to the top x a controlling, fatherly male lead

A low-status, delicate, calculating, flirtatious heroine. The male lead is impossible to seduce at first, but eventually lowers his head for love.

Age gap, size difference, an old flame rekindled

The heroine is inspired by the type of female lead in the extra chapters of Green Tea: a genuinely calculating, status-seeking beauty who loves money.

I'll post the full blurb before the story starts.

Theme: May the world treat you gently
