Citrus - Season 1 Episode 7 -

Feeling downhearted after Mei tells her to end their kissing habits, Yuzu comes across her childhood friend, Matsuri Mizusawa, becoming perturbed when she hears about her dubious methods of earning money. After glancing through Yuzu's phone, Matsuri catches onto her crush on Mei and almost forces herself onto her until Yuzu receives a call from Mei. Noticing Mei across the street, Matsuri forces a kiss upon Yuzu in front of her. The next day, Matsuri shows up at Yuzu's school to invite Yuzu on a date, effectively declaring war against Mei.
