• 'Will it reach you?' - Actually....i planned to write it as 'will it get through to you' as in the feelings...i think 'get through to' sounds better/prettier though meaning is same as reach...but....bcuz the song's conveying it in layered metaphors and connecting to the first line 'if i spread my "wings"...'...i think i should use the term that matches 'wings'....so 'reach' is appropriate i guess.
• 'kanjita nukumori' - warmth felt....but i think it'd be awkward to have the warmth felt that had been touching you....of course warmth can be felt right? (it's warm) so i omit kanjita...it still sounds kinda awkward but i'm trying to comply with all the grammar/tense used though they might not even meant to mean anything literal....bcuz songs vocab sometimes defy the politically correct rules of grammar...they just want to make it sound good...but i'm not sure if it's always the case or not...so i might as well, present it as it is...unless it sounds too horrid then i'd change a bit. Like 'the warmth had been touching you'...yes, in the lyrics, it's in progressive past tense, as far as grammatical rules go...i'm just not sure if in its context the grammar means anything or not.
• I think 'overflowing from deep inside the heart' would make more sense...but again, just complying with the grammar...

 [V1] 

• 'demo' can mean 'even though' other than 'but'....so it could also be 'want to meet even though can't meet'...i used 'but'...but i think...both have same impact...
• 'Kokoro ore-sou ni natta hi mo aru' - i omit 'sou' and 'mo' direct use from this line....or it'd sound 'There are also days when it seem I had became heartbroken' or sth...but that sounds too cloggy right?

 [V2] 

• 'Sabishisa to itsumo mukiai' - is just 'Always facing loneliness'...i added the 'Having' so that it'd flow better with the nest line...
• 'egao' - can be smiling face or just smile
• So for this whole stanza/verse I'm guessing he's saying that He couldn't meet this person he wanted to meet(from what we learn in previous verse) so he's lonely...but seeing this person's smile allow him to have the spirit to keep living(how does he not get to see the person but can see the person's smile? Well, his 'wings'...so he's flying and seeing this person from afar...remember? xD) - of course, that's my interpretation bcuz damn that's what deep/flowery/layered words are for...interpret.

• 'hitoribotchi' - the state of being alone/lonely....
• 'Kitto iki rarenai ikimonodakara' - in many/all of online translation....dakara is translated as 'because' though the dictionary says it's 'therefore', 'so'....so i try to go back to the context of the song and how the lyrics flow so far...
• Another overall interpretation for this verse bcuz i find this one of the most difficult verse...first of all, i find it a lil weird that Jungmin sings it...not very accordingly to the lines distribution....did you notice that he pauses after starting one word from the next line? like instead of singing 'Sou hito wa hitoribotchi ja' he sings 'Sou hito wa hitoribotchi ja kitto'....but i try to ignore that instead of bringing forward 'kitto' into the first line's translation...the first two lines are so hard to make sense for me though....but after going through it over and over...i feel that the lyricst is trying to make the lines sound like the singer is pondering over something...and when you ponders, you don't always sound articulate or organized right? I feel like it's designed as if he's slowly conveying his thoughts...bcuz if you separates them, they sound kinda wtf...but when you combine all the lines as a sentence...it does make sense...wanna try?

翼広げて この空を抜けたら

Tsubasa hirogete kono sora o nuketara

If I spread my wings across this sky

あなたに届くのかな?

Anata ni todoku no ka na?
