Save yourself. The protagonist saves himself in his previous life, why? Because he has gone through hardships and ups and downs in his previous lives, and there is no good result in each life. Now someone gives him a chance to save himself in every life as another person.
Intention: No one loves me, I can love myself. No matter how many shortcomings and advantages there are, no one loves myself more than me. Maybe I don't understand myself, but I know what I want to do next moment.
