Fairy Tail: Lost One - Chapter 31: Back At Fairy Tail

Wan Tong was bound by the “Corpse Collecting System” and travelled through various small worlds. Her mission is to use the big boss’ white moonlight’s body to resurrect and stop raiders from looting the big boss’ luck.

Wan Tong : Didn’t you say that the big boss has no emotional line?

System : Who brought the white moonlight back to life →_→

Wan Tong : …. sob, sob, every day I try my best to help the boss deal with the raiders, but the boss is thinking about how to attack her!

PS :
(1) The male lead is the same person, the white moonlight is the original MC, which is mentioned later.
(2) Every world is probably sweet love

T/N : white moonlight = first love

A man who was once called the world strongest agent ended up becoming a teacher after his retirement to train the new generation of agents. After many years of training his disciples, he is killed at the age of 60 by the ploy of a secret organization and was reincarnated in another world with all his past memories.Though he was surprised by the magic and the strange species of that world, he adapted very fast to his condition as a newborn and took advantage of it. He acquired special magic and gained a massive amount of strength thanks to his tight discipline in order to reach his goal: resume his career as a teacher which he left halfway through in his previous life.This is the story of a man who based on the memories and the experiences of his previous life, became a teacher who travels through the world with his new students.

Deek has never had success with the ladies. He’s poor, overweight, and generally unliked. Feeling like a burden on his mother, with his life going nowhere, he spends his days playing video games. However, when a mysterious game ends up in his bag, he is teleported to another world. The only way for a talentless slob like him to get by is to venture into dangerous dungeons for fame and money. Regrettably, Deek always preferred to play support roles, and in this case he picked White Mage. In a world with slavery, where he can purchase beautiful and powerful women as his allies, this might actually work.
