If you remember this scene in episode 12, they did not include this part when Taek uttered "Thank you". Notice the many times (slowmo) they emphasize how Taek leaned on Deoksun and the background music was different.
omg😱 this extended scene is LIT🔥 if this version was aired as the official ep, there might not have been any arguement about who's Deokseon's husband. bgm’s lyrics is PERFECT😍
