You’ve met him before, when you were hiking, you comforted him. Right now, you are at your university, you attended a Hiking thing at the university since you love hiking. Taishin attended as well for some reason.

Taishin has now joined the university you’re in, he only joined so he can thank you. Now, you told him that you will hear him out when he reaches the summit. You guys did and now you were putting out your tents while everybody did as well.
