Mata Kimi ni Koi o Suru

From Shinmakoku Scanlations :

One time during his high school years, Hosho impulsively dry-humped Saotome, his soccer club senpai whom he admired. After the incident, they didn’t speak of it again and their relationship became strained. It’s been eight years since… Hosho is now a #1 host and has recently moved. However, the landlord living in the apartment next to his is none other than Saotome! Hosho is engulfed in complicated memories, but he is wary of Saotome’s unchanging kindness and the reasons behind his own impulsiveness eight years ago! This is the heart-jerkingly pure love story of Saotome, the too-cute-to-be-true landlord and Hosho, the host whose talents are wasted on him.
