The kid next door came back as an adult. What he is aiming for.. is my ♡♡..?! Choi In-Ho, the kid next door who took care of him when he was young, appears in the basement of this ordinary office worker. Due to In-Ho's fraud (?), he suddenly ends up living in the basement. In-Ho, who has been in love with the kid since his childhood, tries to seduce him, but fails once and for all. What do we do to flirt with this dull brother?! (Source: BOMTOON, translated)
