It wasn't often that Lan Wangji left the Crystal Vales. Since he had arrived he'd definitely done his fair amount of travelling, but more than once he gravitated back toward the Vales where he seemed to feel most at home. Not to mention he and Wuxian had actually begun making their home, after a scuffle with a ghost and being able to sooth it, it had led them right to a settlement they could use. To make home. It was a fair bit of work since it had been abandoned, but when you had the famous Lan sect arm strength, heavy lifting was a piece of cake, not to mention fast travel was pretty handy too.
He'd left Wuxian back at the Voiceless Heights, right where the settlement was, though he was sure the man would be roaming around and doing what he liked. Wangji on the other hand had set off to Pandopolis, wanting to scout out the large library once more and see if there was anything useful he could check out, or even from their own world. He'd stopped by the galactic garden first, marveled at the wonderful and odd flora they had, some he had never seen before in his life. The cultivator had found there was a shop too, with lotus seeds, the man not even needing a second longer to think before he bought a few packets, making his way onward to the library soon after.
Wangji was surprised to find there were books he recognised this time, ones literally from the library pavilion he missed so much. As shocked as he was, he was happy too, running his hands over the familiar silk work around the spine and binding, so distracted that as he walked out from one of the aisles he very nearly bumped into someone. Stepping back immediately, Wangji bowed his head to apologise only to find himself looking at very familiar robes, the same blue and white, making him tip his head to one side before his gaze trailed up to see who was wearing them.
His heart told him who long before he saw with his own eyes.
"...Sizhui." He whispered, dropping his arms to his sides and the items he was holding with them, clattering to the floor at their feet. Lan Wangji didn't often make shows of emotion or surprise like this, but he thought he would be forgiven this once, even by Uncle Qiren. Lunging forward this time, he wrapped his arms around the young boy and pulled him in against his chest, one hand pressing against his spine while the other rested at the back of his head.
"You're here... You're really here, Sizhui." Wangji whispered as he squeezed his son to his chest, his hand smoothing over the boy's hair a little while longer before he finally, slowly pulled himself back.
With his hands on his star disciples shoulders he gave him another squeeze, his golden eyes a little more brighter than usual, from tears unshed, but he figured his son would forgive him this once. It wasn't like it was the only time he had seen him in tears after all, not to mention previous occasions had been so much worse. Reaching one of his hands up, he cupped Sizhui's cheek in his palm and felt the familiar warmth just beneath smooth skin, the elder actually smiling, wide and bright, to the point his eyes disappeared into nothing more than crescents.
"How long have you been here? Have you eaten? Are you hurt? Is anyone else with you?" Wangji asked, brushing his thumb across his son's cheek one more time before he let go, quickly picking up the things he had dropped while he waited for answers.
