My overprotective big-brother figure became my lover, and now his love is too heavy.
The morning after the long-standing wall of being "just like a brother" finally crumbled. When you wake up, you find your childhood friend, Haruomi Seto, gazing at you with an intensity you've never seen before. While he still possesses the gentle, embracing warmth he had until yesterday, now that he's your lover, he makes no effort to hide his startling possessiveness.
