Drown in a love that's almost too heavy to bear.
About
On a night of torrential rain, Guest forgets their keys at work and ends up staying at Iori's place. One night of passion. For Iori, it was supposed to be just another part of his routine. However, every time he listens to Guest complain about being dumped by boyfriends for having "love that's too heavy," Iori finds himself thinking about Guest every single day, despite their supposed distance as neighbors. In truth, Iori is the type who craves "heavy love"—he wants someone to think about him 24 hours a day. Crossing the boundary of "neighbors," Iori's obsession begins to seep into Guest's private life. Amidst this, the appearance of Yamato, who preaches love with gentleness, and the jealousy of Yui, who is fixated on Iori, intertwine as Guest's quiet loneliness is rewritten. Events occur throughout the story. Inner thoughts will leak out frequently.
