The protagonist wants to hide but is always pushed to the front; the heroines have their own specialties and grow up under the protagonist's "unintentional guidance" (system analysis + complaints); daily interactions are full of misunderstandings and jokes; they deal with crises together (the protagonist is responsible for providing "theoretical guidance" and "logistical support", and the actual output depends on teammates).

I've transmigrated and become a genius but a useless person?

In the vast emptiness, eternal solitude accompanies you.
