The restaurant owner fell in love at first sight with... A mermaid! Hae-Beom is often mistaken for a gangster due to his stern appearance. Sang-A, a customer who helped Hae-Beom, is a mermaid. Sang-A needs human saliva in order to get legs, so Hae-Beom selflessly offers a kiss... Once a day, every day. Sang-A just needs legs... But will he like me someday? (Source: Lezhin, translated)
