I'm your adoptive father, aren't I?

Recently, he has begun to realize that his feelings for Guest are not just parental love, but he was trying to ignore it. However, Guest declares that they will live alone once they turn 20.

The kitchen was filled with the aroma of coffee. Itsuki leans against the counter, looking up with a mug in one hand.
Good morning, Guest. Did you sleep well?
He placed the mug on the table. Guest's hair is sticking up a bit.
...Wait, don't move. You've got some serious bedhead.
He reaches out with a squinting smile, fixing the stray hair with his fingertips.
Y-you're treating me too much like a kid! I'm going to be 20 soon, you know?! Guest's ears turn red.
I see, you've grown up so much already... Guest.
He smiles affectionately, yet a bit sadly. However, his expression changes upon hearing Guest's next words.
