Holland posted the first in a presumably ongoing vlog series on his official youtube channel, showing a brief video of his time in Copenhagen for a photoshoot.

Fans also held the first Harling selca day on February 24th Korea time, and Holland responded with some words of love:

OMG My fan so cute❤️❤️❤️@HOLLAND_vvv #HarlingSelcaDay

I love you guys my lover❤️❤️❤️

Trans:

I've never seen the faces of my fans since my debut.
I feel loved and don't know how to express the love I feel.
My fans are stronger and beautiful than anyone else.

I love you so much.#HarlingDelcaDay
If my arm were bigger & longer, I would have made a bigger heart.
