Genshin Impact: Why Are Your Health Bars Showing?

I'm a new author and not very good at writing, so please bear with any plot holes or inconsistencies.

Male lead: Zhang Yu'an (Lowell). Female leads: Furina and Zhang Ruoxu.

No romance.

Lots of original worldbuilding, proceed with caution.

The ending is partly happy and partly tragic.

Updates are irregular. The author may take a long time to revise a chapter or because of schoolwork (a really long time).

The atmosphere is rather heavy.

(!! Don't fall for the male lead. Don't fall for the male lead. Don't fall for the male lead.)
