็ใใใใฆใใ comes from ็ใใ (to keep alive or let live) in the passive form, so it means โbeing kept aliveโ or โbeing sustained by someone.โ In the song, the singer says he is living because of the other person, giving this phrase a powerful sense of gratitude, dependence, and emotional survival.
"13 Years Old Night" is push pull pot looking back at one day that split a childhood in two. The time stamp gives it away: "14ๆ46ๅ ใใคใใจ้ใ้ใ้ณดใฃใ" (At 2:46 p.m., a bell rang that was different from usual). In Japan, 14:46 is the minute the Great East Japan Earthquake struck on 11 March 2011, so the singer is telling us he was thirteen that afternoon. The chorus asks the listener straight out, "็ช็ถใในใฆๅคฑใฃใใใจ ใใชใใฏใใใพใใ" (Have you ever suddenly lost everything?), and answers for himself: "13ๆญณใฎๅใฏๅใๅ ฅใใใใใชใใฃใใ" (at thirteen, I had no choice but to accept it). He is honest about the empty comfort people offered, too: "็ก่ฒฌไปปใฎๅคงไธๅคซใ ใใใซ้ ญใ้งใๅทกใฃใ" (an irresponsible "it's okay" kept racing round my head). ๅคงไธๅคซ (daijoubu, "it's okay") is one of the first words learners pick up, and here it stings.
What pulls him through is one person's smile. "่พใใใฉ ใใชใใ็ฌใใ ใใง ๅใฏๆใใใใใใ " (It's hard, but just you smiling seemed to save me), and later the much heavier "ใใชใใซ็ใใใใฆใใใฎ ๆณฃใๅซใใ " (I'm being kept alive by you, I screamed and cried). I like the small changes across the choruses: "ๅใๅ ฅใใใใใชใใฃใ" (had no choice but to accept) becomes "ๅใๅ ฅใใใใ ใ" (I accepted it). There is also a nice idiom, "้ๅปใฎ่จๆถใจใซใใใฃใใใฆใ" (even when I stare down my memories of the past). ใซใใใฃใ is a kids' staring game where the first to laugh loses, which makes "่กจๆ ใฒใจใคๅคใใใชใ" (my face doesn't change at all) land harder. The song ends moving forward: "ๆใใชใใฐไธ็ทใซ็ฌใฃใฆใใใ" (if you're scared, let's keep laughing together), then "้งใๅบใใ 13ๆญณใฎๅค" (I started running, that night at thirteen).
