Avatar of the Sun in Twilight [English]

A seal that houses part of the sun power, has a host who has been imprisoned a long, long time ago, although he doesn't know it since he just woke up. (This is an AU, the mc didn't transmigrate, it's not a harem and I don't know who will be the romantic interest, if everything goes well it will be 3 chapters a week although it can change depending on the situation. any criticism will be gladly accepted, but I ask you not to be so hard as it is the first time I write) (the rights belong to their respective creators, the cover image is not mine and I found it on pinterest, if the author bothers I will remove it without problems) (I'm not a native English speaker, and I'm using a translator so I'm sorry for any mistake)
