Ryusei Fukada of the hugely popular five-member junior idol group ACEes takes on his first-ever leading role in a continuing television drama! Fellow member Hidaka Ukisho (ACEes) joins him as his love interest in a heart-fluttering youth home drama and romantic comedy. The story follows Natsuki Takemiya (Ryusei Fukada, ACEes), a third-year high school student preparing for his university entrance exams. Right before summer vacation he is dumped by his girlfriend, and his mock exam results are nothing but failing grades. In the midst of this disastrous situation, his sympathetic older sister arranges for her college boyfriend, Sota Kobayakawa (Hidaka Ukisho, ACEes), to become Natsuki's private tutor. At first Natsuki finds the almost-too-refreshing Sota hard to like, but a sudden smile from Sota, or the innocent way he pats his head and says, "You worked hard!", make his heart skip a beat. Falling for his sister's boyfriend should be unthinkable -- so what is this feeling!? He is supposed to be focused on exams, with no time for romance... Yet confusion and conflict keep building inside Natsuki. Enjoy this refreshing story, perfect for summer, in which fluttering feelings burst and fizz like sparkling soda -- on Blu-ray!
