The Solution to my Equation

Two

The contest was over, Team Beep having lost. The contestants returned to their respective 'homes', with the two hosts slowly walking back to their shared residence. The silence between the two has heavy, with X occasionally stealing peeks at Four. His head was bowed, arms loosely crossed, obviously in thought.
X let out a soft sigh, looking forward, and stepping up into the large house's porch. He opened the door for Four, who walked inside with a small but gracious smile. Closing the door behind him, X immediately steered Four to his room, despite his incessant protesting. Pushing him into a baby blue room decorated with various images of the two together and several math-related posters, X pulled the complaining digit to the large bed in the corner. Despite how much he had complained and argued, Four gladly crawled into his soft, pale blue bed at X's command, falling face-first into the pure white pillow.
With a faint smile, X tucked Four in, and was about to leave the room when a soft voice called him back in. "Hey, X... if it's not too much to ask or.. too weird... would you mind sleeping in here with me..?" The nervous shake in Four's voice made X's heart melt as if he had just seen a puppy.
"Of course, Four." He murmured with a faint smile, gently clambering onto the bed beside Four. Thankfully, there was enough room for both of them. Immediately, Four latched onto X, resulting in a surprised squeak and a small sigh of air from X. Four drew him close, burying his face against X.
"Sorry... I just... really need this." He whimpered, body starting to shake. Alarmed, X hugged back, quickly whispering soft reassurements to the unstable number. Eventually, the shaking stopped, what grew to become labored breathing calming down, and the pressure around X slackened. Sighing in relief, the small variable pressed a gentle kiss to Four's forehead, before settling up against him. Within minutes, he was asleep as well.
