THIS IS MY FAV QUESTION SO FAR instantly i thought of it's the falling in love !! reason being that i feel like taro as a person is so loving and the way that he utilizes his energy is by giving love to others and he gains energy from receiving it [from my observation]. i think think this song perfectly suits him bc the lyrics talk ab always falling back in love even if it usually turns our negative/isn't worth it, and taro has expressed his mentality of putting your all into everything even if it doesn't work out. i think he would apply this with love as well, and considering who he is as a person, he will always fall in love with SOMETHING. it's just his nature. he's just so full of love. that's what i think.
