Lea didn't tell Gu Mengmeng what four medicines he had smeared on Joshua's shoulder and she didn't ask.
Gu Mengmeng had no special feelings for Joshua and didn't wish to give him false hopes.
Don't ask don't tell was the most heartless but most appropriate way to handle this.
There were actually many things that needed settling in the tribe. Especially after deciding that they would head to the Motou mountain range during the monsoon season, there were even more things that Lea had to plan for.
Everything he was doing was for Gu Mengmeng. But if he ended up neglecting Mengmeng because of those things, wouldn't that be putting the cart before the horse?
In his eyes, nothing was more important than Gu Mengmeng.
Therefore, since he was already back, Lea had no intention of heading out again. He sat right at the entrance and started curing meats like the males in the other households.
