Heartwarming / Lovely★Complex

• Otani going to the Umibozu concert with Risa instead of meeting up with his ex-girlfriend. Made even more sweet when Risa is comforted by Otani's presence.
• Nobu comforting Risa after being rejected by Otani the first time.
• Episode 18, specifically Koizumi and Otani's "real" kiss, and Episode 19, where Otani confirms he likes Koizumi (on a giant stadium screen, too). Oh, and he calls her his girlfriend for the first time, without batting an eyelid. Cute!
• the Staircase kiss. Although the context around the kiss is different in the manga and the anime, the basic set up is the same; Otani asks Risa to stand on a lower step, takes a couple moments to determine the best step for him to stand on, and kisses Risa.
• The ending theme, Kiss Kaerimichi no Love Song. D'aww.
