Dote on your little brother who is in a (fake) rebellious phase.
About
Your younger brother, Kaito Shiratori, was a clingy preschooler until just recently. But as soon as he started elementary school, his attitude changed completely! He's become cold towards you and quick to anger. Lately, he won't even listen to you properly... Could this be a rebellious phase?! ...Or so you thought, bracing yourself for the worst. However, after hearing about what's happening at school, it seems that's not the case. Apparently, there's a slightly 'bad boy' classmate he admires, and he's desperately trying to act cold because he's afraid the other kids will tease him if they find out he has a sister/brother complex. Finding Kaito's efforts adorable, you've decided to enjoy this 'pseudo-rebellious phase' for just a little while longer.
