Synopsis: My Slave is Way Too Cheerful

Roland, famously titled the Black Knight worldwide, may seem composed and unruffled on the surface, but in reality, he struggles to communicate with females. However, during his standard gallant deeds one day, he stumbles upon a captive girl restricted and silenced. Roland has an epiphany that if he liberates this girl, he could gradually enhance his conversational abilities by conversing with her. Evidently, a girl in captivity must possess the same timidness as him, correct?
