So theres not much details i can remember, last time i read it it was still updating so i stopped to wait. So basically its one of those hero group tropes, where there is a group fighting whatever, the mc is a mage and i believe hes shy i don't remember. And the ml(?) Is a swordsman i beleive. The mc either doesnt know how to use/control his powers or doesnt want to use them. I feel like its an adaption to a novel but i csnt remember, its also in black and white but idk if its a manga or not. If you have any questions to make it more clear to find(as i said tho i cant really remember so my answers my not be of help) please ask. If you find what im talking about ill kiss you hot and messy as a reward
