• So yeah, im about to write a letter to my crush who is Japanese.. But Itsao hard for me to translate some of these.. "How come you have enough time to go out and make other girls fall in love with you, but you don't have enough time to pay attention to the girl who already is." "The worst way to miss someone is when they are right beside you and yet you know you can never have them." "I get the best feeling in the world when you say hi to me, or even smile, because I know even if just for a second, I crossed your mind." PLEASE? Anyone? :( advance THANK YOU!! A big thank you

• Answer:

  遊びに出かけては女の子を虜にするのに、 なぜ、すでにあなたに恋してる子には振り向いてくれないの、、、 一番辛いのは、好きな人がそばにいるのにそれが叶わぬ恋だってわかっている時 あなたが声をかけてくれた時、微笑みかけてくれた時がこの世で一番幸せ。 たとえ、それが一瞬でもあなたと心を通わせられたから、、、
