Haru to Natsu

In a bizarre turn of events, Makoto finds himself drawn to Haruna, a kind and reserved girl he meets while volunteering at the school's athletics festival. After confessing his feelings to her, she unexpectedly rejects him, only to later call him and ask him out on a date. The reason behind her mixed signals is soon revealed: her twin sister Natsumi, a feisty and mischievous counterpart who delights in embarrassing and teasing Haruna. As Makoto navigates the complex and often hilarious dynamics between the sisters, he discovers that Haruna is not to be underestimated, and that her tough exterior hides a fiercely determined and independent spirit.
