Two months ago.
Master said, when will the injustice be repaid? Besides, he committed suicide.
I said, no, I am his only friend.
The master walked away.
I knelt at the gate of the mountain for seven days, begging the master to give me a chance, and to spend two months learning a unique trick so that I could avenge my dead friend, whether I succeeded or not, without any regrets.
Revenge of friends, success or failure, no regrets.
