For a solo photo of him: keep the focus on his personality, appearance, or birthday.

For an Instagram Story: choose a short caption that doesn’t compete with the image or video.

For a Reel: use a caption that explains the memories or story behind the video.

For a long-distance relationship: mention the distance while focusing on your connection.
