Yesssss! Thank you so so much youre a lifesaver now i have to eat this in one
Ive been wanting to reread this one bl manhwa but i cant remember what its called for the life of me, if anyone could help me out thatd be great?
Its kinda system-based where mc has to play as different characters and fulfill a requirement before he moves onto the next character, and the seme follows him through each story. As far as i can remember they start as step-brothers, and further along in the story theres a chapter where hes like a sentient aquatic kind of tentacle monster experiment? Haha typing it makes it sound insane but its hooked in my brain lol any help is appreciated
