Shouichi, aged 29, is the eldest son of the Honda family. He is actually Kenzou and Shunji's cousin, adopted into the Honda family after his parents died when he was an infant. Working as a tax official, he is known for his rigid and no-nonsense attitude towards collecting payments.
Throughout his childhood and teenage years, Shouichi struggled with stalkers and his own romantic feelings for Shunji. These feelings eventually led him to agree to have sex with Shunji on the condition that Shunji would leave the house. When they meet again ten years later, Shouichi decides to secretly date Shunji, not wanting to live with regrets.
