Oyaji Hiroimashita
The first hald of this is about Ryouji, an exhausted, divorced salaryman who collapses in front of a mansion and is taken in by the mast of the house, Ryuunosuke. Ryuunosuke is a rich high schooler who fell in love with Ryouji at first sight. They're cute together, but it felt like their relationship progressed way too fast. The second half of this manga is about Nakaya, Ryuunosuke's servant, and Mashita, a high school boy and friend of Ryuunosuke's. Mashita determinedly pursue's Nakaya, getting jealous of how much attention his friend gets. Nakaya is a big tsundere. I liked their story a little bit more.

EXCELLENT artwork but the translation is a little... funky. This is about two actors. The younger one supports the shipping of them together, even writing fan fic himself lol Eventually they hook up but the younger actor gets upset that the older one is now working with someone else.
