Yep. I am willing to try a season 2 of My Happy Marriage since I think there is still good story potential there. However, the first season is really a mixed bag. Episodes 1-6: great storytelling while Episodes 7-12: pretty disappointing. So, if I watch season 2 and it looks more like the second half of season 1, I will probably bail.
As for vending machine, I am 100% on board. I already made a comment about my feelings on the announcement post. I have started keeping coins on hand to be ready to insert them when season 2 drops.
This and Frieren are the two I am most anticipating. Eminence looks to be keeping a nice pace this season, adapting only 1.5 LN volumes over 12 episodes. Should set things up for a dramatic finale once again.
