!! My AU !!
As far as he knows, Mercury technically is a nobody. A side character. He's just that person in the sidelines who only helps develop the main protagonists, not to mention that he's also the therapist and the one who has to carry everyone's baggage. Everyday he puts on a smile, but is it really real?
Earth always thought he was destined for something. The others doubted him at first about this "legacy" he has created in his mind, but that didn't stop him. After all those hard centuries of hard work, it finally paid off. He finally had organisms that he can take care of. Recently though, after a regretful mistake, Earth starts to wonder if he's really capable of having sustainable life or if he should do something more about it.
Two struggling souls encounter each other during a very hard time period. Will they be able to heal each other, or will it lead to more risks and dangers?
(This story is happening during and after the Earth Alone Arc, but in my AU!)
