Man up for her sake, boy. I want to see you put more effort into it! Seems to be the start of a new arc. This time set in Aoi's side of the world. I'm already expecting the next wave of love rivals, quite possible some arrogant rich dude is going to oppose them next.
Eiji's mom was an angel, she truly loved her husband leaving behind a life of riches. It's sad that she died young, but maybe she at least died happy. Better than living a long life that she'd have hated if she were married off to some rich, ugly bastard she didn't love.
Don't use your son's life story for your novel, it's too generic and full of cliches.
