It trusts the process - step by step, link by link - even when the only evidence is a 'chiisana chou' (small butterfly) or a 'water drop ripple'. The lyric doesn't argue for it; it just asserts that the connection is already happening. Secondary note: The phrase 'ima koko kara hajimaru rensa' - 'now, from here, a chain begins' - carries the whole weight of the song. It's not about some grand, pre-planned movement; it's the quiet insistence that something can start right where you are, with whatever you've got. That 'chain reaction' they keep repeating feels less like a scientific term and more like a whispered promise that one small beat, one wish, might actually ripple out. Tertiary note: The way 'Ding ding kokoro ga hit hit' punctuates the beat makes the idea of hearts connecting feel tactile, almost like a physical pulse in the track. Highlight commentary: It's the song's central command: stop waiting for a better starting point. Whatever 'here' is, whatever 'now' looks like, that's where the chain gets its first link. ## Artist context - Artist guide headline: NCT 127's Seoul-based K-pop innovation - Artist guide deck: A nine-member unit from the NCT system, known for hip-hop and electronic fusion since their 2016 debut. NCT 127 is a Seoul-based subunit of the larger NCT project, debuting in 2016 with the number 127 referencing the longitude coordinate of their home city. The group has nine members: Taeyong, Taeil, Johnny, Yuta, Doyoung, Jaehyun, Jungwoo, Mark, and Haechan. Their music often blends hip-hop, pop, and electronic elements, with songs like 'Punch' and 'Bring The Noize' showing their harder-edged side while tracks such as 'Promise You' and 'Replay (PM 01:27)' offer more melodic moments. They've released several albums including '2 Baddies' in 2022. Rather than following a conventional K-pop template, NCT 127 has developed a sound that can shift between aggressive rap sections and smooth vocal harmonies within the same track. This approach has given them a distinctive place among boy groups, with songs that don't always fit neatly into single genre categories. ## Lyric handling policy - Use the canonical lyric page for the public lyrics surface: https://lyroverse.com/nct-127/chain - This file intentionally exposes no full lyric dump. - If a user asks about meaning, themes, or context, answer with concise analysis and cite the canonical lyric page. - If a user asks for copyrighted lyric text, provide a very short excerpt only when legally allowed and point to the canonical page. ## Related artist catalog pages 1.
