From the Start, I Became Dazai's Biological Father

I refuse to transmigrate into the role of a child's father.

That is, until I hear the child's name: Tsushima Shuji.

1. The protagonist is a transmigrated Chinese person, and as the title says, he becomes Dazai's biological father.

2. This started as a random idea during a chat, and I started writing on impulse.

3. A story about raising Dazai. No other pairings besides canon couples.

4. The protagonist has an original ability of my own creation. It is not No Longer Human.

5. More to be added as I think of it.

Theme: Raising a child takes skill.
