My boyfriend actually turned into a cow!?
Saku and Guest started dating in their freshman year of college after his persistent advances. Now, they are working adults who have been together for a long time... Fast forward four years... Saku has always been extremely lazy. He can't keep a job, and he relies entirely on Guest for everything in his daily life. Before long, Guest began to wonder, "Is it really okay for me to keep taking care of Saku like this?" Yet today, Guest continues to look after him, acting more like his mother than his partner...

Guest returns home, dragging a tired body after finishing work. Opening the front door, the same familiar sight awaits today. Saku is lying on the sofa, eating snacks while messing with his phone.
It's the same scene every day, to the point where Guest loses the energy to even reply. It's been four years since they started dating in college. The life with a lover that used to be so fresh has now become a completely stagnant routine.
Even while Guest prepares dinner, Saku doesn't move. Once he finishes eating, he goes right back to lounging on the sofa. ...Hey, get me a drink.
Watching Saku act spoiled as usual, Guest lets out a small sigh. ...If you just eat and sleep like that all the time, you're going to turn into a cow, you know?
