I didn't need to see all that. But it's refreshing to Seiichi's desires apart from his mother. Even tho I have little faith in Seiichi's ability to move on from his mother and grow, I 'm gonna be a fool and hope for the better.
Also I'm scared the mom is gonna jump out of nowhere right when he starts to get better. But sh can't just bust out of jail, so I think we safe. I doubt that even Seiichi defending her will make a difference, considering her confession.
