(You are Frank in this. Enjoy:D or suffer. Because 70s logic.)

So Eddie has a crush on you,but never tells because of you and Julie being a "couple"(maybe not really? I don't know). So he keeps it as his forever secret.

He wanted to tell you how he feels, or maybe write a letter, or anything but..he couldn't. He doesn't want to end your and his friendship.

So you had finally notice why is he a bit down..
