Shiro wasn't sure why it started, but he does know how and who started it.

Lance, in all his pyjama glory with his blue slippers, burst into the common room where Shiro was currently relaxing in and demanded him to give him a goodnight kiss.

At first, Shiro was confused and wondered if Lance had finally lost it. But when he saw those anxious eyes, he knew that it would become something that he would frequently do for the blue paladin.

With a smile, Shiro stood up and approached Lance, agreeing to his demands.

A part of Shiro felt extremely embarrassed but the smile that Lance had given to him when Shiro had agreed had made him push his embarrassment away, happy to know that he at least were able to make sure one of his ki-teammates will have a good rest.

Following Lance to his bedroom, Shiro tucked Lance in with a hint of amusement and kissed Lance goodnight on his forehead, wishing him sweet dreams. Lance replied with a contented sigh, murmuring a 'goodnight' to him sleepily.

When he stepped out of the room, he was a bit startled to see Hunk, looking shyly at him in the hall.

"Umm... can I have a goodnight kiss too?" he asked shyly, blushing a little.

Shiro had to hold back a chuckle and nodded his head. Hunk beamed at him and proceed to drag him to his room.

Shiro did the same thing to Hunk, wishing the teen sweet dreams and stepped out from the room, a smile of happiness stuck on his face as he made his way towards his own room.

After a few nights of tucking and wishing them a good night, Pidge and Keith found out about it and demanded the same thing. Pidge, demanding it loudly while Keith asking him hesitantly.

Being the kind leader he is, he gave them what they wanted, and soon, it became a common thing for the black paladin to tuck in and give a goodnight kiss to each paladins.

Of course, both Alteans found it very cute and endearing. Allura could not stop smiling at him when she found out while Coran just congratulated him, saying how proud he was to finally see them being a proper family.

Although embarrassed, Shiro didn't really think too much about this new routine they're doing, thinking it's just some ways he could help his fellow teammates.

But that all changed when they decided to have a movie night.

Thanks to Pidge's brilliance and Hunk's miracles, they were able to set up some sort of projector that could project the movies clustering in Pidge's laptop that she brought along, among other things.

Snuggling in the couch, the paladins relaxed in their seat and enjoyed the night, once in awhile explaining something to the Alteans when they asked about the movie.

Maybe because of the training they had earlier, Shiro noticed that the young paladins had been drooping, eyes barely open to watch the movie. Shiro smiled at that and carefully shifted their positions so they could fall asleep more comfortably.

Since he's trapped by the younger paladins around him, he gave each of them a ruffle in the hair. "Goodnight, you guys." he said in an endearing tone.

"Night, dad..." was what they answered in a sleepy state, sighing contently as they burrowed and leaned into Shiro, who had gone rigid in shock.

Slowly, Shiro relaxed and let his lips curled into a content smile, his chest feeling very warm and nice when he heard that.

"They really like you, Shiro," Allura commented softly from the side, Coran agreeing with her. Both Alteans smiled happily at the paladins that had become a family to them.

Shiro hummed in agreement, his eyes slowly sliding to a close. A rumble from Black had soothed his mind and finally, after what seemed like a long time, Shiro slipped into a peaceful sleep filled with streaks of vibrant colors, promising a better tomorrow.
