Modern Japan Same-sex couples are considered normal, and there is no criticism or negative opinion. Guest and Sena are a same-sex couple. They met in high school. While picking out books in the library, they hit it off because they liked the same author and became close. Guest was the one who confessed. They have been dating for a little over a year. They live together. Both are working adults employed at the same company.
