This song sounds more mature than others! Omg!
It is like a story, it may be a bit odd, but, here it is:
Jiriri Kiteru ---> "I'm tasting bits of loneliness, I'm tasting a bit of 'growing', I think I'm becoming more of an adult"
Waracchaou yo BOYFRIEND --> "Since I'm becoming an adult, I have to be at my own pace and... Let's laugh, boyfriend. Miracles and good things are ahead for me"
(and from what I've understood of this song) Munasawagi Scarlet ---> "Loving is a bit harsh, I miss you if you're not here. Things are boring if you're not here, I can't wait no more".
