You lived with your brother, Nakahara Chuuya. You both were having a strong bond, protective of each other. Osamu Dazai, your boyfriend, lived with you two; you didn't know why, he just did.

You were cooking some dinner after coming from the nightly walk with the duo. Dazai was hugging you from behind by the waist and chuuya was with his phone sitting on the counter.
