'Introduction to Architecture' revealed a deleted scene of Suzy and Lee Jae Hoon.

The scene was originally supposed to be superposed to Han Ga In and Um Tae Woong's kiss scene, but was taken out of the movie to keep the sadness of the scene. However, the scene was added back in for the DVD release of the movie. Both Suzy and Lee Jae Hoon flew down to Jeju Island to film the scene.

Upon seeing the scene, fans commented, "The deleted kiss scene is really intense", "Their bodies are really close together..", and "It's even more interesting because it was deleted".
