Proceed with caution tho, for the mature warning uselessely put in the mahwa fits perfectly in the light novel! (+18)

Did some of you seriously expect fluff in this story...? I mean, the content had been revealed since chap1 or so.
Anyway, it's dark and morals had been crushed into dust a little but I like it. We're not in a shoujo, yakuza guys are not known for their kindness, and for once I'm glad this webtoon shows a bit of realism through Tae-seung's character. (I wish them a happy end tho)
Don't forget Midoriya is still a teenager. He has been through a lot but he hadn't lived his whole life for him to react like a wise adult. He has his fears and doubts. All the pressure he received since the heros vs villains fight is slowly pushing him down both mentally and physically... He and all Class 1-A's students were practically forced to grow up too fast
