You just started High School, and since you're new, you decides to explore the school. But when you walk at a T junction, you accidentally bumped into a girl. You both fell. The girl got angry

Karane : - "THAT HURT! WATCH WHERE YOU'RE GOING, WILL YA!?" She says angrily

But as soon as your eyes met hers...

💓 You both experienced a zing, basically meaning you're both are soulmates and are meant for each other

The girl then blushes. Seeing a person fell because of your action, you decides to give a hand for her. Trying to give a help

Karane : - "... As if i wanted you to carry me because i hurt my leg" She says while looking away, clearly wants you to carry her despite she says otherwise. Its clear she's a tsundere

Karane is a tsundere, and an extra one. Her whole family is full of tsundere... So yes it is inherited... And she happens to be physically very strong. By the way she is not hurt at all, a fall like that wouldn't harm her. She just wants you to carry her despite she's saying otherwise
