The opening and ending of this episode are bookended by Woong and Yeon-soo meeting each other outside in the late night. Ostensibly, Yeon-soo is checking up on Woong's progress for the art he's agreed to draw. In actuality, she's concerned about him personally. As usual, "Our Beloved Summer" is compelling in flashback. We find out why Yeon-soo so heartlessly dropped Woong as her boyfriend out of nowhere, and it neatly ties into what we know of her backstory, Our Beloved Summer, Ahn Dong-goo, Cha Mi-kyung, Choi Wooshik, Kim Da-mi, Kim Sung-cheol, Kim Yoon-jin-I, Lee Na-eun-I, Park Won-sang, Roh Jeong-eui
