About the Drama 'Natsuiro Kumo ga Koi to Arashi o Makiokosu'

### Story

The protagonist, Natsuki Takemiya (played by Ryuhei Fukuda of ACEes), is a high school senior preparing for university entrance exams. Just before summer break, he is dumped by his girlfriend and scores all E-ranks on his mock exams—facing the worst possible situation. Out of concern, his older sister arranges for her boyfriend, Sota Koizumi (played by Hioki Uda of ACEes), a university student, to become Natsuki’s private tutor.

Initially, Natsuki finds Sota too cheerful and dislikes him. But when Sota flashes an unexpected smile or innocently pats his head saying, 'Good job!', Natsuki’s heart skips a beat. How can he fall for his sister’s boyfriend? What is this feeling? He’s supposed to focus on exams, not love. Confusion and inner conflict begin to stir within him…

Despite knowing he shouldn’t, Natsuki can’t help but see Sota shining brightly. This delicate summer romance and personal growth unfold under the backdrop of clear blue skies and fluffy white clouds. A refreshing, sparkling story perfect for summer, where heart-fluttering emotions fizz like sparkling water.
