Man I feel bad for Ryouji, he's always trying to ask Nozomi out when he gets a chance to speak privately but it'll never happen. Because she doesn't want to and after school, she's always putting on a "show" or more for Kimio when they get home.
Man's either really dense and doesn't know despite our MCs having a reputation of being the best couple in school as mentioned by Mitarai earlier, or he's hoping to try his luck since they're not officially dating.
