S1E16: The Meteor Shower

Thyme lost 4 years of memory, and that included Gorya. Thyme's mother took this chance to educate Thyme on becoming the successful heir she always wanted. Gorya sneaked into Thyme's room, wishing to recover his memory. But it didn't work. Gorya stood in front of Thyme's house for hours after being kicked out. Thyme's mother questioned Gorya why she's so determined. After being scolded by Thyme, Gorya gave him back the necklace.
