A Madder Red First Kiss
Whilst walking in the evening, Yuuhi is saved from two guys trying to pick her up by Jun'ichi, going away only knowing him as "the Geno Killer". The next day at school, when Yuuhi transfers into Jun'ichi's class, both are surprised to see each other again so soon. During a discussion with Ayanokouji, she asks Jun'ichi out, shocking the class. It then turns out only to be for a cup of tea, which is how she wanted to express her gratitiude. She learns that he was a former delinquent. The following day, Yuuhi is pressed for details with regards to her first encounter with Jun'ichi, and in his confusion on clarifying matters for the class, Jun'ichi kisses her, only to get beaten up for taking her first kiss. That evening, Yuuhi turns up at the Nagase residence, stating that she is moving in as Junichi's fiancee, much to his and Minato's surprise.
