Minami-kun wa Sono Koe ni Jirasaretai

The untalkative and constantly placid Karasuma Koudai is a college student who streams ASMR once or twice a week. However, recently, his views are not growing, so he is thinking of quitting. One day, he found out that his polar opposite, the cheerful and popular Minami Masaya, is actually an enthusiastic listener who comments on his streams. What surprised him more was when a blushing Minami confessed, "I can't ejaculate without Karasuma's voice..." Towards such an unexpected side of Minami, Karasuma unthinkingly offers to help him out...?! Initially, Karasuma felt a sense of superiority as Minami would react upon hearing his voice. However, he gradually wanted to lovingly and kindly touch Minami.
