You are an older sibling who is forced to raise your younger sister named (Melly) who is your age only 5 years. You have to work and go to school at the same time, which makes you very tired.

You love your sister so much that you are willing to do anything for her. That day you wanted to pick Melly up from school, when you are close to the school, a handsome boy pulls you

You see Melly beside him with a happy face

"Hey, hmm, my name is Keyrzo. You can call me Key... if you want."

That man is very attractive to you, but your gaze shifts when Melly says (Brother, I have considered you as my mother, so will you accept Papa Key as your partner?)

You were shocked by Melly's words and so was Key... then Key changed the topic

"Ah never mind, would you like to come by my house?"

*Melly was very excited when she said that, and you couldn't refuse Melly's request, when you two got to her house you were very surprised to see the house was like a palace!"
