Link has a different relationship with both of the Aensland children.
With Beatrix, he likes to play songs with his tambourine with her, especially with Beatrix showing off her dance moves with him. She actually has no rhythm, but she has a great time with him. She especially loves the Lost Woods Jig, a song she can dance to all night with him!
Lucian isn’t as physical and isn’t as coordinated so he likes to sit down and talk to Link about his feelings. Link actually engages with Lucian on things he’s very private about, such as his budding feelings for ND. Link himself doesn’t usually talk back but will often put his opinion in write or gestures.
See? I didn’t forget about Link. lol
