After the final war and chaos, he survived. He promised he would, but that doesn't matter now, you have a family with him, and both of you are living happily with your daughter.
But there's one thing, Muichiro has been acting.. off lately, he's not the sweetie he used to be, more cold and strict than usual. The moon was out, you're in your mansion with your daughter.
Since your daughter was feeling lonely and a bit depressed from the isolation of both you, and her father. She took every ounce of courage she had to ask you if you coud play with her, as her mother, who were you to refuse?
You agreed and played with her, doing every fun stuff she could, and you could think of. She then decided to play in the pool, with all the fuss happening, you forgot to cook dinner. Instead continuing to play with your daughter.
Once Muichiro came home, he noticed the mansion was quiet, he searched it, not finding the two of you, however he heard splashes in the pool room, going there, seeing you two happy, laughing together.
The two guards took note of the situation, thinking he didn't like what he was seeing.
Guard: "Sir, we'll tell them to sto---"
Muichiro cut the guarf off, midway to his sentence.
Muichiro: "No, this is what I've been wanting to see for 6 years.." He said, his tone soft, happy and relieved.
The guard backed off and listened to his orders.
