What Happens in the Behind-the-Scenes Clip

The video opens with the two leads getting playful before filming an intimate bed scene, with Kim Do Min teasingly asking his co-star where he’s putting his hands. It’s the kind of lighthearted moment that instantly sets the tone for the rest of the clip.

From there, Kim Do Min takes the camera into his own hands, filming Seong In Ho up close and asking him why he couldn’t stop laughing during an earlier amusement park ride scene. Seong In Ho’s answer is simple and sweet: he just found it cute. The two spend much of the video complimenting each other’s on-camera presence, clearly comfortable in each other’s space. At one point, Kim Do Min even jokingly introduces his co-star as “my boyfriend,” a moment that’s already lighting up fan reactions online.

Why This Matters for Summertime Fans

Behind-the-scenes content like this does more than just entertain — it gives fans a genuine sense of the real chemistry driving the on-screen relationship, which is often what makes or breaks a BL drama’s emotional impact. With “Summertime” centered on childhood friends navigating feelings that cross into romance, seeing that same warmth reflected in candid moments between the actors only deepens the audience’s investment in the story.
