Moving around the mystery person was certainly seeming to be working in his favour; with another figure bounding up to them, Ciel knew having a conversation with one person let alone two whilst so unprepared would have given him something to lose sleep over. However, despite the exceptional results he was receiving from his strategy of avoiding people, the words of a confession elicited a stumble in his step - walking into something so private between strangers certainly wasn't his goal for the day, but the almost instant realisation that followed kept him from rushing to be on his merry way. He may have been blind - quite literally - but he wasn't deaf, the two people just a few meters away were unmistakably Niles and Deuel. Duel. Who confessed to Niles. And Niles. Who was being confessed to.
It made sense. With six of them being childhood friends it was inevitable that at least some of them would catch feelings for each other, but for one reason or another, Ciel found himself approaching the two in complete disregard for his previous apprehensions. Whatever emotion that threatened to bubble over was shoved behind a casual albeit brisk gait. Fists clenched within the pockets of the short-sleeved hoodie he donned, he managed to ignore any of the following exchanges from either of them and twisted his features into a semblance of a friendly smile, chirping, "I see you two are collecting kindling, too? You know, with the amount I've found I think we can head back and start a fire now."
Completely bulldozing over Deuel's heartfelt speech made him feel like shit but hearing one of the potential answers Niles could give would be worse; if anything, Ciel was simply looking out for his friends. Making sure no hard feelings got in the way of spending some time together before they parted ways, it was simply him being a good friend. Besides, he didn't even hear Niles' response so how could he be held accountable for interrupting a potentially significant moment? No matter how he purposefully focused on the blood rushing to his ears or the tightening grip he held on his collected firewood, it was simply a coincidence he didn't hear him, don't worry about it - with night falling he was simply tired as anyone else would be.
"I'm sure everyone is getting cold by now so we should be getting a campfire going soon," he contentedly nodded, as if agreeing with his own suggestion and aptly positioned himself between the duo lest they end up realising their requited feelings for each other and running into the sunset hand in hand. Although, with Niles involved, such a situation seemed to be a dubious outcome but Ciel didn't particularly feel like taking the risk, just in case. The cool breeze that signaled the encroaching starry sky did little to calm the heat he felt building within his chest and cheeks, though, he hoped the low light and refusal to keep his gaze upon either Deuel or Niles would be enough to mask the awful sensation from both him and his friends.
