Mada Kimi wo Miageteru

Having given up on his dreams and returned to his hometown, Keita reunites with his high school classmate, Tsubaki. Back then, Tsubaki would always whimsically mess with Keita while he quietly drew illustrations in the corner of the classroom... Between Keita, who failed to become a manga artist, and Tsubaki, who is burdened by her own particular circumstances—this adult gyaru and otaku are legit starting their lives over!
