Can someone update me in the current NJPW scenario?

I lost a few shows in the last 3 months or more, but I search sometimes to know the champions and the factions. Anyway, I don’t know which are the current storylines and how the BOSJ League went. Last thing relevant I saw was Ryohei Oiwa turning heel, aside from that I don’t really know who is feuding with who or if someone else joined a faction or id have a new tag team. Someone can tell me the last relevant moments and stories??
