Shishunki no Zawazawa

Shirasaka is a high school student who has been feeling increasingly anxious and unsettled lately. His close friend Kuroda, who already surpasses him in both academics and sports, has recently undergone a sudden growth spurt, making him look more mature. This change worries Shirasaka, who fears being left behind. One day after club activities, while Shirasaka is taking a nap, Kuroda unexpectedly kisses him.
