Tehodoki Koukan ~Boku no ga ○○ ga ×× de Tomaranai yo...~

Takuma was living happily with his stepmother Sayuri, their feelings for each other finally mutual.
Then, one morning, he got a call from his best friend Kenji (Minami Uchida’s stepson), who told him that his parents were getting a divorce.
For a moment, Takuma wondered if it was his fault, but of course, he couldn’t say that out loud.
His mind raced with thoughts.
…I hope Minami and Kenji can find happiness, like me and Sayuri. Maybe one day, the four of us can laugh together.
After the call, Takuma spent his usual sweet time with Sayuri. But in the middle of it all, Minami suddenly showed up.
After some back-and-forth, Minami ended up staying at the Honjou household for a while.
And just like that, a strange love triangle between Sayuri, Minami, and Takuma began.
