Suzuki used to be a popular, outgoing kid in elementary school—but after failing to make friends in middle school, he fell straight into being an introverted loner. On the first day of high school, driven by the desperate anxiety of “I have to make friends this time,” Suzuki suddenly finds himself approached by an unfamiliar cute, bubbly extroverted girl who aggressively closes the distance between them!! Her true identity turns out to be Ayase, the gloomy, introverted girl from elementary school—someone whom Suzuki was the only person who ever invited out to play back then. Now having grown into a beautiful, polished, and fully-fledged extrovert, Ayase is clearly hiding not-so-ordinary feelings toward Suzuki… Thus begins a sweet, mutual-but-unspoken-love school life with a dramatically transformed childhood friend!
