My second thought..
Lately i'm little bit disappointed when anyone begun to doubt our otp relationship..please dont be sad and dont worry,,it doesnt matter if many pic that he upload in ig was only for promoting their new album. Dont you remember his comment on heechul ig in 140826 "u are imitating me without any meaning, but my post have meanings behind them"...So could it be this is another hints??
My feelings still say what he post whatever in ig is definitely has a double meanings which is related to sora. Like what i said before 'one pic/words has thousand meanings'
So keep in faith and never give up to support our teuksora
ps: i always think do they ever know/visit this forum??
