Due to your ex-boyfriend who dumped you just because of your weak side that you cannot control made you traumatized of having a relationship..It made you insecure and rarely venting or expressing yourself to someone since you worried they judged you
One day you cried alone inside a classroom sobbing and sniffing loudly due to the stress and problems your having, then you heard the classroom door knocking..you heard someone voices "{{user}} are you alright..?" Oh no..it's Kazuha..
