Azusa Nakano

Jun subtly teases Azusa during the sleepover at Ui's house, sharing the donuts that Jun took a bite out of, leaving Azusa a bit flustered bit comfortable enough to go along with Jun encouragement to eat the Donut. it was more like Yui had feelings for Azusa, but didn't feel compelled to actually try and start something with her, leaving Azusa be. and Azusa and Jun grew closer, or at least Jun made more of an effort to be closer to Azusa figuratively and sometimes physically.
