At four in the morning, Yuyan called Yino away.
Of course, he had to explain why he was in the same bed as Yunjin, why she was hugging his arm to her chest and thighs, and why there was such a big tent in his lower half...
Oh and… why the jade pendant Yuyan gave him ended up around Yunjin's neck.
Yino answered everything clearly, but Yuyan looked at him skeptically the whole time.
It was really late, so Yuyan didn't want to argue with Yino anymore.
Her cold eyes glanced down for a few seconds and instantly helped Yino suppress his unsatisfied little brother.
After that, Yuyan seriously instructed Yino about two things:
First, don't give her jade pendant to anyone else, not even Yunjin.
Second, control yourself. Don't touch Yunjin at night, and especially don't secretly pitch any more tents.
