Helppp

Hello! I'm trying to find this isekai where the MC was "accidentally" transported along with the female class president and male vice president of his school. It turns out the female class president has lightning abilities, the male vice prez is the hero, while our MC is a healer. But he has to go through hellish training with the ex-commander whose name I think is rose. She is missing one eye and created the whole idea of training a healer past their limits and healing themselves. In the rest of the countries, healers are seen as inferior bc they can't use any other magic. This ring a bell to anyone?(づ￣ ³￣)づ
