One word:Epic. Not too much character development aside from Oyaji, but what did you expect, its only 25 chapters. Its a great short story, realistic, telling us about the real world, the filth, the worker class people and their everyday struggle to survive. A man who deply loves his family and who would do anything for them, a kindhearted man, that looks like a bear. And with a backround not so healthy, wet, he managed to become a real family man and protector. 10\10 overall, if someone wants to read a heartwarming story, not romantic shit, but realistic hard life, its it worth spending2 hours of your life reading this manga.
