Konya mo Kimi ni Knockout: Toshishita Boxer ni Dekiai Saretemasu

For some reason, Sae, a serious and ordinary office worker, is being aggressively approached by Touma, a popular young, handsome boxer. Sae is actually happy, but she has a problem that prevents her from responding to his feelings... In fact, Sae is frigid, and has never been able to feel good during sex! When she tells Touma about this, he declares, "I'll make you feel good for sure!" Perhaps with this man...? A love story of healing between an office worker with frigidity and a younger, doggy-like boxer! (Source: Kodansha, translated)
