I'm pretty sure they were buried under the landslide from the chapter, but who knows there might be a plot twist
Oh noooo
You can see from the panel where hr wakes up, that the position where his mom and sibling were sleeping on was changed into soil/land, and given the situation, it's probably a landslide.... It was the most heartbreaking thing I saw when I realized this
StAaAaP I also realised this when I reread. I legit cried.
I hope his sister and mum are alright. The Alpha will be like a father to him. This honestly name my near explode
