Hearts2Hearts 하츠투하츠 'Lemon Tang' MV

What happened

SMTOWN released the music video for “Lemon Tang,” the title track of Hearts2Hearts’ second mini album of the same name.

Why Koreans care

Korean K-pop discourse treats “summer” as a recognizable idol-song category, not merely a release season. The commenter’s use of “청량감” describes a bright, cooling, energizing concept and sound; here, the nonstop structure and sharp, fizzy production are understood as reproducing a lemon’s refreshing bite.

What Korean viewers say

Fandom: One commenter singles out a member’s charm rather than analyzing the song: “Ian is seriously so cute.” Fandom: Another focuses on the track’s seasonal identity and relentless arrangement: “Hearts2Hearts really nailed the full-on summer style. It genuinely charges ahead without a break, but that actually makes the refreshing feeling even stronger. The sound fizzes like lemon, so it feels like it’s announcing the start of summer. This is basically set to join the summer-song lineup.” With only two comments provided, no majority view or disagreement can be established.

What you'd miss

“여름 계열” literally resembles “the summer type/line,” but in Korean idol discourse it means a group has convincingly adopted the established summer-concept lane. “추가각” is compressed internet slang meaning something “looks destined to be added,” so “썸머송 라인업 추가각” predicts the song will enter listeners’ informal summer playlists or seasonal canon; it does not refer to an official lineup.
