Good grades, pretty face, perfect body, great  personality. Even Sohyun admires her. Once her and Chanyeol's relationship has been revealed, no one is surprised, but actually happy for them. Others wonder why the perfect Eunji would ever date the haughty Park Chanyeol. Their feelings are tested when Sohyun arrives.
