Honestly bros, the conclusion isn't quite as wild as the journey itself, but I'm really glad Shiina-san found her purpose in life now that her daughter has broken free from the cycle of regret and depression that Shiina-san was trapped in. I'm happy for Kokoa and Tomoko as they move forward, and I hope the man can also move on and take responsibility for his actions in the past, becoming a responsible adult for society. He shouldn't dwell too much on the past that clearly didn't care about him. I guess that's what they mean when they say what goes around comes around, eh... Thanks for the translation!!
