So it makes a lot of sense that Mutsu pushed Mirai away to protect her after what happened to her sister. Unfortunately, Mirai found out what happened to her aunt, who felt more like her actual mom than Mutsu. Some awful parenting, but everything adds up.
For Namu he honored the wishes of Mutsu before he died. The big difference between him and Mirai is that he let go of how he was mistreated, while she held onto that, and it was her whole purpose in life. I think the biggest thing is for Nana to be there for Mirai because Mirai has always been alone.
