For me, no matter how many times Jongup say that he envy Yongguk's deep voice, I know that deep down inside him, he envy something about Daehyun. I've been crossing tons of video and pictures of Jongup stealing glances at Daehyun. I don't know how to inteprete it but that looks like a love glance to me. I mean, he's in love with Daehyun but Daehyun hangs around Youngjae so much so he got jealous, maybe? They can be adorable and they can be awkward together. I love these two so much! No matter what, I will sink with this ship. 

p/s: I feel better after I let this all out. I have no daejong friends, most of them are daejae shippers. I'm all alone. But for me, being alone doesn't make you a weirdo, it makes you unique. Remember that.
