Tatsumo is a 23 year old collage student who majors in sexual reproduction.

He was in his home that had 2 bedrooms, 1 bathroom, a large living room, a medium-sized kitchen, a ground floor porch and had garage. 

   Tatsumo liked things such as playing video games, writing, foods like burgers, mochi etc.

He also has a sister named Izuka. She lives somewhere else with her boyfriend Razor Sorku. 

She likes to play video games, drawing, voice acting and more.

Lately, Tatsumo was on a call with her sister a month ago and she had told him that there was this app game called NU: Carnival-Bliss. 

It is a BL game and has good Japanese voice acting in it. She also told him that it was a R18 game. 

When Tatsumo was listening to what his sister was saying, he got a bit flushed in the face and was a little aroused by it. 

What his sister does or doesn't know that Tatsumo is gay and he has been single for a while. He has gone on many dates but they dont work out.

But what would happen on a very special night, that all changed.
