Disregard, because this is really stupid~

Ok, I was watching Dream Team things, and I noticed someone that for a while I thought was someone else.....I have too much going on to keep up with all the new bands that keep coming out! It ended up being Sanghun(or Sanghoon, however you prefer to spell it) that for a whole freaking hour thought was Jaejin from FT Island.....Can someone please help me out here? Am I missing something like they are siblings or cousins or something.....or do they just look alike? I am attaching a photo, but I also addd in Ricky from Teen Top. Even though the photo of Ricky is when he was younger, it was just to show that they all kinda look similar....I've noticed others stars looking like each other in the past, but I never got confused on one....maybe except Boyfriends Twins, but ive gotten over that now~ Anyways, if you stuck around for my whole rant and the photo then thanks! and if not, ah well~ no harm done, and seriously please someone let me in on any info I may not know! Thanks to all of you!

P.S.-yes now that i look at them both cI can tell the difference....but I dont know....and for some reason im also getting a tiny bit of an affect of Seo Inguk.....aish....I think i'm just tired and need to go to bed...
