@BeyondParasolTrees The funny thing is they didn't even "become" friends. One chapter all three of them are pinning Mo down and twisting his ba***, and then the immediate next chapter, the same three are hanging around Mo acting like they're friends. The author couldn't be bothered to show this friendship developing, so they just skipped over that to get what they wanted.
So, to be frank, they never became friends because the author was lazy.
