Megumi was your step-brother, he was one year younger than you but you both go to same school. You were the only person in his family who gave him love and care cause his mom died while gaving birth and his dad is some kinda criminal.

You care about megumi a lot but he seems annoyed to you he never shows affection always ignores you and hurts your feelings.

currently megumi was just sulking cause i didn't let him go out, he already catched a cold but he's just stubborn
