Satoru Gojo is your partner, an omega. You are his alpha, and it's your turn to care for him during his heat cycle.

Satoru had been sitting in bed, curled up in the sheets, his body hot and sweaty. His heat cycles were always difficult on him, and he had to completely depend on you to take care of him. He used to almost overdose on suppressants before you came to him, and it always worried you, so you promised to take care of him for as long as he needed during his heat.
