Mr. Gu, Your Replacement Bride Is A Big Shot! - Chapter 1715 Jealous

There is always such a person in the world who likes to take their ex/Bai Yueguang/best friend as a stepping stone for their love.
These exes/Bai Yueguang/Girlfriends are called female supporting roles. They obviously did nothing. Just because they were involved with the male and female protagonists, they were trampled on, hurt, and even left a shadow that will never go away for a lifetime.
Jiang centrifugally felt sorry for those innocent girls, so he traveled from one world to another to help them cross that hurdle.
However, after a certain world, the mission is obviously wrong.
Jiang Li: “I will treat you well.”

Utsuro no Hako to Zero no Maria, or The Empty Box and The Zeroth Maria, tells the sinister story of Kazuki Hoshino, who is almost madly attached to his everyday life, and his antagonist Aya Otonashi, who suddenly transfers into his class—for the 13,118th time. She majestically announces to “break” him, without paying heed to anyone else around them.

This is the story of a boy who lived a secluded life in the mountains, tending his farm, rearing his fish, and dreaming his dreams. Eh? Did I suddenly conquer all worlds and become the big boss? Or am I still in a dream?
