Raw pls?

I believe it is a story revolving two brothers being sex slave to pay off their dad's debt (not really sure why they were doing that) and...the younger brother does not know about this at first until he saw with his own eyes that his brother is having sex. The younger brother (uke) began having sex to the heir (?) Of the house they're living in. The seme and uke is attending the same school and is in the same class (?). At first, he hated having sex with the seme but I think, they became lovers...? At one point, the uke caught a fever (he didn't say it to the seme) because he slept without his clothes on. And in their lunch break at school, while the seme is kissing the uke, he realized that the uke's tongue is warm then he brought him t the infirmary.

So...who's who? If the teacher is the omega, I'm fucking gonna kill myself.

Pls help me to look for this shounen ai manga: It's the story of siblings where the younger brother kinda hates his older because something happened. At chapter one there was an incident (idk, maybe an earthquake or something) that caused them to be closer to each again like they used to be. This younger brother possess a power that the enemies want to have and the older brother protects his younger brother. In the younger one's body, there are two souls that made the scientists curious and took an experiment on the younger brother. And in one science (experiment scene) the researchers tried to kill this younger brother by locking him up in a room alone with a fox (idk what animal is that) and the other soul on his body saved him.

Please help me. I really want to ready it agai o badly. My memories from it is vague so I'm not really sure on every single detail, that's th best I can remember. Please help......
