Emerald's manga / #bully(95)

Really cute, but its never explained at what point did the ML gain his memories back? Also feel bad for both of them, they suffered over 10 years of mutual pining and unrequited love, all because of misunderstandings and miscommunication. If one of them was straight up honest during elementary, middle school, high school or early adulthood, this could have been avoided. But we'd be missing the drama and plot if they did. Side note, this manhwa has a sequel focusing on the mc's friend and ml's brother, hopefully it gets translated
