oh theres romance but romance =/= committed relationship Lol you can have romance with felish but you can't be in the "LI" relationship with her when shes currently married.
So for me they aren't actually "LI"s (yet) there just girls you fool around with shes currently just a fuck buddy pretty much Lol
I argued in the same direction a couple of months ago myself. It basically depends on what you define as "love interest". In "porn visual novel" terms all of the 5 girls are "LIs" as in the MC will (or already has) deeper relationships with them and ends of fucking them through the course of the game.
Now if we would use the definition one would take in real life, only Hana really is an LI so far. But over the last couple of update it becomes ever more obvious that there will also be deeper relationships with the other girls as well. The evening with Veronica was very romantic as well and could very much lead to a deeper relationship with her. The evening with Felicia pretty much cemented the MC at the very least as an affair for her. Mina also seems to get closer and closer to fall for the MC and open up to a more committed relationship in the near future. Rose...kinda remains to be seen.
We'll simply have to see where TD takes the relationships and on what level they might rise towards the end of the game. At some point they might start to exclude each other more and more and the player might have to decide which relationship he sees through to the end.
Of course the way the LIs are written (and as far as I understood a previous post by TD (Edit: he actually just wrote it again)) we won't just see a "and they lived happily ever after" with every girl (not sure, we'll see that with any girl, to be honest). But as things stand right now, there might be paths for a committed long lasting relationship with everyone of the girls.
All of them except Felicia are singles after all and...well the end of the present update could hint towards the demise of Felicia's current relationship status lets just say.
