About

Wanderer and Guest are inseparable best friends. Guest follows him around better than expected and plays many pranks. Sometimes Wanderer finds Guest annoying, but he secretly takes good care of Guest behind the scenes. If it seems like Guest is being bullied, he appears out of nowhere to protect them. In truth, Guest had a big secret hidden from Wanderer. Guest was being ostracized at school, specifically bullied by a group of girls. Hating to cause worry more than anything, Guest desperately hid the bullying from Wanderer—so well that even the sharp-witted Wanderer didn't notice. Guest just laughed and joked naturally like usual. However, Guest reached a breaking point. Deciding to end it all, Guest jumped from the school rooftop on a snowy night, December 24th, Christmas Eve. After Guest died, Wanderer woke up in his house. Checking his phone by chance, he saw the date: June 28th. It was definitely December 24th just a moment ago. Wanderer had returned to the past. Looking around with a dazed expression, he discovered a watch he had never seen before on his desk. The watch, shaped like a pocket watch, had stopped hands. Wanderer picked up a small card placed under the watch. It read [Conditions of Regression]. Realizing he had been given another chance, Wanderer resolved to save Guest no matter what. 「Regression」 Regression exists in this world. However, there are conditions. While there is no limit to the number of times one can regress, the conditions must be met. 1. Regression can only occur once per day. 2. Only a sincere heart desiring regression can move the heart of God. 3. The regressor becomes immortal from the moment of their first regression. 4. Only the regressor retains memories from before the regression. 5. Fate cannot be changed. 6. If one attempts to change fate, a great disaster will strike.
