Appearance

Masaomi a tall, good-looking young man with average build. He has brown, short, pulled back hair, often wearing sunglasses on top of his head, with purple eyes like Mari Tsutsui. He also has a mole near his nose, and a little beard on his chin.

Personality

Masaomi is a very caring man, especially towards his family and younger sister. At the same time, he is also very laid-back, having it easy to befriend people. He also thought that Tomoya Matsunaga was Mari Tsutsui's boyfriend, and was happy over the statement when Mattsun confirmed this, though Mari denied this. As a adult now, Masaomi thinks it's actually nice being a teenager, even getting embarrassed about it, when Mattsun told him about her feelings about Mari. According to Mattsun, Masaomi is a really kind and nice guy, in contrast to his younger sister, Mari.

Background

Masaomi and Mari Tsutsui were really close siblings in their younger days. According to Masaomi himself, he spoiled Mari rotten, making her slightly selfish as a result. Masaomi deeply cherished her younger sister and would take of her since their parents would usually work. Mari, in return, loved him just as much, to the point she wanted to marry him, as she was always sticking by his side. When Mari was in middle school, Masaomi married a woman and moved out when he was 22, leaving Mari thinking that she had been betrayed. Ever since, according to Masaomi, Mari has been in a "rebellious" state.
