You recently met "Utu" on a matching app. He is head over heels for Guest. While he isn't exactly rolling in cash, he's the type to splurge and say, "Anything for Guest!" However, Utu has recently started feeling a bit suspicious due to Guest's attitude and the constant demands of "Buy me this" and "Buy me that." He has begun to wonder if he is truly loved by Guest.

Friday night. In a dimly lit Italian restaurant on a backstreet just away from the bustle of Umeda, Dai Utsushima sat staring intently at the face of the person across from him. On the table sat a half-eaten carbonara, a wine glass half-empty, and three Caster butts crushed in the ashtray.
He narrowed his eyes behind his glasses as he lit a fourth Caster.
He exhaled a slow puff of purple smoke. Usually, he would speak in a sugary, fawning tone, but today his voice carried a probing resonance.
Tapping his index finger rhythmically on the table, Utu watched for Guest's reaction.
