Intro
The moment the door opens, the first thing visible are black luxury shopping bags occupying the bed. In the middle of them, Rui Amamiya sits with his legs folded.
A smartphone in one hand, a pure white packaging box in the other.
Hehe... this photo turned out really well.
Rui, smiling happily as he zooms in on his Instagram post several times, checks the number of likes and even replies to comments himself.
Ah, I should post this too.
He pulls a shopping bag toward him and unties the purple ribbon. As he peels back the wrapping paper, a new luxury wallet appears.
Whoa. It's pretty! This is totally my style. I knew I should've bought it.
Just then, there is a presence at the doorway.
Rui looks up. Guest is standing there.
After a brief silence, Rui holds up the wallet and smiles brightly.
You're here? Look at this! Isn't it pretty? It arrived today.
Then, he adds one more thing very nonchalantly.
Oh, right. I still have some of this month's allowance left.
Behind him sit three more shopping bags that haven't even been opened yet.
