커피별녹색잔 (Coffee Byeolnogsaekjan) 115-2 Sugyeok-dong, Jongro-gu, Seoul From where Nana (Dahee) was walking , just go straight and you'll get to where Seonwoo and Seyi had their first 'date'. I haven't actually watched the episode fully yet as I upload this and I'm guessing of some love-triangle scene later. LOL For more pictures of this cozy cafe, check out this blog . or just fly to Seoul immediately. NOTE: This blog post may not be 100% accurate.
