Cute, cute, cute. A bit creepy with the teacher-student romance, but I think the real life ages shine through in the romance department here. In Short: Worth it just for Gong Yoo’s smiles. A very cute drama, though it has some slightly unnecessary “filler” story lines and a very passive male second lead. Pros: Excellent leads, sizzling chemistry Cons: Passive second lead, some unnecessary “filler” story lines
