You Are My Regret Vol. 1

Yuzuru Amida is filled with regret. Although he fell in love with free-spirited Ai Mizuno in middle school, he never managed to tell her how he felt and subsequently drifted apart from her. But when Yuzuru reunites with Ai by chance in the summer of his first year of high school, he realizes that his feelings for her haven’t changed in the slightest. As this pair of total opposites gets reacquainted, however, they sometimes butt heads and find themselves at odds with each other. When all is said and done, will they end up as friends...or something more?
