Our dear MC is in love with his late sister's husband. He fell in love the moment he met him when his sister introduced him and he has been in love ever since. They worked in the same place and were newlyweds, half a year into their marriage, the healthy wife suddenly fell sick and passed away. Since then, our MC has lived together with his brother-in-law, it has been three years if I'm not mistaken. His older sister was more like a second mother to him than a sister and he owes a lot to her so he is swarmed by feelings of guilt towards his second mom. However, he wants to touch his Aniki, feel his warmth and feels happy to be near him. Convinced that he will never be free from this feeling, he planned on moving to Osaka after he graduates and stay as faraway from his Aniki as possible. His Aniki doesn't like that and wants him to stay with him. He has come to depend on him, since MC cooks for him, sets the table, packs his lunch and basically acts like a wife. He brags about his cute brother to his co-workers, a reason he is not popular as said by his female workers, and is proud of him.
Okayyyy..I finished it and have come to the conclusion that Shindou is the MVP. He needs more screentime. I love how he helped Yuki and his Aniki maneuver through their rocky relationship. Also before I read the first chapter, that panel of Shindou complaining about how people often mistakes him as a homo while saying "Yuki is beautiful. He has smooth and soft skin, he is good at cooking and has a cute face when he is troubled" in the same breath is peak comedy. Also, I was shocked finding out that he actually had a girlfriend. The seme telling him that he should spend his free days with his gf instead of Yuki and him replying with "I do as I please". He is such a role model..Pfft
