What would your avatar do in this situation? (Read the lore first)

Long ago... 2 races lived in harmony. Humans and monsters. They lived in peace until the great war had started causing chaos throughout the lands. Fortunately, the monsters were able to make a peace treaty with the humans with a condition for them to live in the underground forever. But after a few years have passed, the monsters abandoned human kind after suffering from discrimination, abuse, and shortage of resources causing them to seal the entrance to the underground preventing traders, visitors, and leaders to meet up until the magic seal has been lifted. But before this, a human fell into the underground without supervision were he would fall to his death causing a controversy in the entrance of monster civilization. This was one of the lesser important reasons why the underground was sealed. To prevent any further fatalities and major injuries.

Even when his body died, his soul tried refusing eventually merging his corpse with the flowers to create Flowey. Now he lives in the underground where the monsters are now at the brink of extinction were he would live the life he wasn't able to experience before.

His personality is a kind charming kinda fearful comedic person that doesn't fight even when needed to.

His magic is flower magic not plant magic. The difference is that he can only summon flower related attacks, defense, and support magic. Were as plant magic can use Vines and different types of plants, leaves, trees, and aswell as flowers.
