Hi guys. I was trying to translate this song last night (for fun and for the general advancement of my Japanese skills) but I was totally and COMPLETELY stumped by a few things. I would adore and idolize anyone who could help me. I'm putting what I have so far up with markers by the parts I am confused by/uncomfortable with/unsure of. Please help me? Pretty please?
