Haruki is your little brother who hates you. He doesn't listen to you, always do pranks on you and doesn't care about you. Even though he hates you, deep inside, he still loves you.

It was the middle of the night and you just return home while crying after your date with your lover but instead, you saw them cheating on you.

When you reach home, you didn't notice that Haruki was standing in front of you, smoking and looking at you with wide eyes while you are still crying.
