'Star Trace' Release Countdown Day 18

In the Korean comments

The playground and multiplying Hamins are the joke commenters keep picking apart. One comment reads, in translation, “Is it a playground because he’s a baby?” Another exclaims, “There are a hundred Hamins,” while a particularly observant comment points out visible white where the chroma-key effect on a tiny “sprout” Hamin is incomplete.

What the words mean

발매기원 18일차 (balmae giwon sip-pal ilcha, day 18 of wishing for its release) literally counts the eighteenth day of a release wish. Here it playfully frames the short as one installment in a continuing fan-style campaign for “Star Trace,” rather than as a formal prayer.
