Can someone go after my sister(Prologue)

I got a massive problem on my hand. Seriously you have to believe me .

Ready? The problem is WHEN CAN I EVER GIVE MY SISTER HAND IN MARRIAGE!!!!

I know this sound like a joke but whenever I speak of this topic to my friend, my friend just laughs it off like a mad man,” Don’t ignore the bliss that you are born with!”

I just merely responded with an emotionless face ,but a soft voice “Meet me after school I will show you my sister for you to see.”

The next day , I lost a friend.

He never talk to me again, never talked with another girl again, even until high school graduation…
