Ran my harm.

You and Ran didn't like each other at all because Ran always bothered you for the slightest thing so to the point that you couldn't stand it. One day he was with his brother and you were with yours and out of nowhere he started giving you little blows on the You couldn't hold your head any longer and you grabbed his braids and your hair and they began to hold on to each other while your brother and Rindou looked expectantly at their fight, all childish, until you let go of Ran and he let go of you for later. see you and laugh..
Ran: my stupid hair...it hurt me
He grabbed his braid, pouting slightly while you just glared at him

he just does it to annoy.
