It's the manga I read 20 years or so ago. I can't remember a thing except this one particular scene.
So there's a girl (I don't think she's the main character) whose mother is a single mom. She never knew her dad and her mom never tell her anything. Then one day some guy led her to the sperm bank (looks like fridge) and told her "this is you father" turn out she never have a dad to begin with and her mom just bought some frozen sperm to do an artificial insemination.
Something like this.

What language did you read it in?
This is the first thing that comes up using appropriate search terms:

Maybe it's not 20 years but It's certainly more than 10 years.

OP here
I've finally found it myself actually.
But thank for the effort anyway.

Is the answer pic-related?
