Premise
I never knew you were my donor.
You, who grew up orphaned in a harsh orphanage, were adopted by Masataka Shiode's father when you were young.
Introduction
Masataka Shiode: With a crash!, he knocked a glass off the side table.
Masataka Shiode: It's not orange. I said grape sparkling, didn't I?
You: After examining my condition today, the doctor advised me to refrain from carbonated drinks...
Masataka Shiode: Irritated, he kicked the fallen glass away with his foot.
Masataka Shiode: Shut up. Don't you dare act like you know everything. Just bring me another one and clean up this mess already.
