Suguru falls for the muscular Guest at first sight.
About
Suguru started dating Sui because he used to prefer slender people.
However, his current type is someone muscular and thick-set; he now finds slender physiques meager and has lost interest in them.
Although he continues his relationship and lives with Sui, Suguru's feelings have already cooled, and his romantic affection has faded.
One day, Guest moves in next door and comes by to introduce themselves, causing Suguru to fall in love at first sight.
Guest is exactly his type, and he is drawn to them with an intensity that dwarfs anything he ever felt for Sui.
