Even if Master's plight was a bit wretched.
He might have been mostly melancholic, but that's not to say he spent all day hiding and crying.
Does the old man know you always say he's crying behind his back?
Oh, he probably knows, but to them, this darling of the Taoist temple, Little Old Man indulges him a lot. He might have been looking at Jinjin with sheer joy, but once Jinjin says anything about him crying, he might just turn around and really perform a crying act for the little guy.
Especially knowing that his life pattern was unusual, Little Old Man also missed the little buddy quite often, but he continued to restrain himself, and so master and apprentice communicated solely through video calls.
"They're not that psychologically fragile."
In the end, Ye Changan couldn't help but defend his master and apprentice brother and subtly defend himself as well, for he always felt that in Little Milk Jin's eyes, he might be perceived in a similar way.
