I'm Actually the Heroine's Kid Who Dribbles the Ball and Runs Around

Unexpectedly, the vicious female supporting character in the classic dribbling novel "Master Chu's Runaway Sweetheart" is reborn!

(Cold and domineering little girl x warm and sunny gentleman) Concept: What you think is darkness, we are all sunshine
