JS said he would wake up in the morning and search for his name on the internet. He is happy if there is no news relating to his personal life and he is fine if the news are work related only. He is a private person in this sense so don't expect too much for him to reveal much of his love life directly in public.
SH only revealed that she was in a relationship before only early this year. Other than that we don't know about her love life unless she wants to share that information with us. She is a private person when it comes to her love life.
The last time that they showed us their warm affection (to me at least) in a public event was during the SBS Drama Awards 2014. It's a sad fact but give them some time to stabilise their "close friends" relationship first (either like IU & Jang Ki Ha / JS & LBY). Let's enjoy and support their individual activities for the time being.
Also LOL most of us must be thirsty for their sightings and subtle hints...I could tell coz "I hear your voice" (my theme for now lol) I went to search for their news all over the places with the cool search engines and SNS but darn I didn't find anything more than you already know. The last sighting of SH was at the airport and that JS has rejected the "One Line" (he must need more free time haha) and went to have "eels" after revealing to the MC he has no plans yet for his next project (ok let me believe him for a few more days). Did they meet? We can live in our dream hehe...not like anyone is likely to know than those 2 cuties.
Ok, enough of blabbing that is partly in my imagination lol. Here is another MV, a nice one again with the song "I Like You", perfect for this dreamy post of mine...
