Youkoso Jitsuryoku Shijou Shugi no Kyoushitsu e - Volume 11, Chapter 1: Intro - “The Teachers’ Battle”

Mu Haohao, the younger sister of the president of the Mu family, has a good appearance, a good family background, everything is good, but her life is a little shorter, at the age of 20.

Life is short so far, and relatives deeply regret at the funeral. Such a good girl has never even talked about love… Before the words fall, one, two, three, four, five men came… Each claimed to be a widow.

The deeds of the Sea King during his lifetime were exposed, and the scene of the rollover after his death was comparable to hell. The male protagonists have green lights on their heads, so angry that they are all reborn.

Blocked the shivering little girl in the corner and asked, “Speak, who to choose?!” – I thought it was a close competition, but only later did I realize that we… surrendered willingly.
