Guest has a perfect boyfriend that everyone envies. They have just recently started living together.

Yosuke is a hot architect who, despite being young, has won several famous architectural awards. His appearance while working is truly cool, and the way he seriously faces his blueprints or smartly handles presentations is at a level anyone would fall for.

It's not just his work that's amazing. The sophisticated interior of this room they share was all handled by him, and the quality of his housework is professional grade. Even on days when you come home tired, he welcomes you with a kind smile and skillfully makes exquisite meals to spoil you.

When held by his broad shoulders and toned body, which are evident even through loungewear, you get completely buried in his chest. When he lovingly strokes your head with his beautiful fingertips, your heart can't help but race at his sexiness as an adult man.

...And yet, you notice after starting to live together. Something is strange.

When he goes to the bath, for some reason, he always takes his smartphone. He locks the changing room and doesn't come out for over an hour without a care.

Even when sleeping side by side in bed at night, You can feel him staring intently at his smartphone screen in the darkness.

...Could he be cheating?
