The update is indeed 99.9% club oriented and even Hana's development is framed in the context of her relationship with the club/her father, so if the club dynamic disinterests you or hugging Mina is your primary goal, you probably won't enjoy this update as much I'm afraid. I've actually been a tad worried of disappointing people in this regard, but the structure of the story is rigidly set in that Saturday of each week is devoted to a copious amount of big ugly sex.
Hi! I truly doubt that more than a few fans will be disappointed with the coming update. While Mina is always very huggable, it is a fact that weekends are devoted to Club activities and we saw in the former updates that all main characters get their time to shine. But it is impossible that all characters get equal screentime every update, I am sure the Mina fans will get more Mina Time in update 3/5 or 4/1. Besides, from a pure story standpoint Mina needs time to decide if she stays with Ian or jumps wagon to Edwin.
My top three are Hana, Feli and Rosi, so I can look forward to the new update!
As for the Club generally, it is the anker point of the story and I am looking forward to see how Mina reaches "Pale Carnations" orbit, esp. since she has the fewest contact points of all main characters. But then again, it might be just gut feeling, but IMHO over the run of the game I think I saw that there is quite a wild side in her.
Hana, for instance, is obviously a wild one, but that is only one facet of her. If you play her route, we see that she is a pragmatic, intelligent young woman for whom a stable life and family are very important and that there are limits to her wildness in some aspects of life, like sex and love.
Mina, who is cute with a capital C, on the other hand grew up rather sheltered, but depending on how you play her route, this shelter was treacherous from what she tells us. Now she is starting to spread her wings and we get the feeling she is eager to "catch up" on life experience, sex too. We see that from her "bucket list", which is rather lengthy and wild and even if she stays with Ian, there are hints during their relationship here and there, that Mina is willing to do "more".
