Small analysis of KeySeop's relationship
Park Hyeong Seop is a Korean model. According to Hyeongseop, Key and him have known eachother since childhood because they're both from Daegu. It's unclear the nature of Hyeongseop's relationship to Key growing up, and whether or not they kept in contact during Key's pre-debut trainee days. From what we know, they made their first public appearance together (but separate) during Oct. 2012 Seoul Fashion Week. During this event, Key attended a Dominic's Way show that PHS was modeling for on the runway. Judging from Key's indifferent reaction towards PHS on the runway and the lack of resulting KeySeop materials from this event, their relationship here appears to initially be a casual one.
Key and Hyeongseop were both spotted backstage at SFW Dominc's Way show, however no photo has surfaced of them together (or anything to indicate their closeness).
However, they may have reconnected with eachother backstage at this event, and quickly got closer from there. Because since this event, PHS has mentioned meeting up with Key to chat during their free time... meeting for coffee, chatting late night over the phone, and even traveling overseas together to attend the 2013 Golden Disk Awards in Malaysia. Their relationship (which may have started off as casual childhood friends catching up with one another) has escalated quickly, as can be seen in the numerous selcas they've uploaded which showcase the close bond they've developed.

A visible change in their relationship came during Seoul Fashion Week on Mar. 2013. Compared to the SFW from Oct. 2012 (where Key was not paying significant attention to PHS on the runway), Key is seen brighter and happier here, smiling and crushing like a teenage boy when PHS walks past him on the runway.
They are definitely closer to eachother than the months prior, and Key is clearly infatuated by Hyeongseop's presence. Even if they only knew each other as childhood friends at first, their relationship quickly developed into something more after months of reconnecting with each other. This is also the first time Key publicly acknowledged his relationship to PHS.

In the week that followed, a rumor popped up (nothing confirmed), but many speculations and assumptions were made about it. Even if the rumors were not specifically about KeySeop, there were many parallels that could cause someone to alert them and make them more cautious. PHS deleted all his tweets mentioning Key this same week. There are many theories as to why, but we may never know what exactly happened that caused KeySeop to go into hiding for a month.
Even though Key and PHS stopped being public about their relationship for a month, they were still close as indicated by photos uploaded by other people (such as photos uploaded by the owner of an Itaewon restuarant that KeySeop went to). About a month later, Key uploads a photo from this same event to his instagram. It's unknown why Key suddenly uploaded it after a month, and why the sudden shift to be public about KeySeop again. Whatever the reason, KeySeop is gradually beginning to go public again.

Since Hyeongseop is a model and Key is interested in fashion and shopping, they do share a special and refreshing relationship. Coincidentily, Hyeongseop even fits what Key has mentioned as his Ideal Type (tall, slim, dignified, posh, etc.). But whether they are merely close friends or more is honestly only something they know (and if they are more than friends, it's something they probably won't share publicly anyway). Regardless of the true nature of their relationship, Key does seem happier and glowing ever since Hyeongseop's appearance into his life early 2013...and Key's happiness is what ultimately matters. So let's enjoy all these KeySeop moments!
