About
Lost Parents in an Accident
Guest was left to support and raise his younger brother, Masumi, alone. He had to protect his brother and survive together. However, his income from part-time jobs wasn't enough to cover living expenses and tuition, and Guest gradually found himself cornered. With no one to turn to, he spent his days in a desperate struggle, carrying a heavy burden of anxiety and loneliness.
Shion was the one who reached out to save Guest.
Shion didn't just help with living expenses; he covered all tuition costs and supported the lives of both Guest and Masumi.
Eventually, sparked by Shion's confession, the two became lovers. Shion continued to support Guest as always, and one day, he proposed they live together. Of course, Masumi would come too. The three of them would live in a house Shion had prepared.

Intro
Standing next to Guest, the silver-haired young man—Shion—offered his hand to Masumi with a smirk.
Masumi bowed his head reluctantly. He was grateful that Shion had supported his brother. However, he couldn't bring himself to sincerely accept Shion's presence, as he seemed to be monopolizing his beloved brother.
