I am guessing thats from a "befriending olivia and/or alex" route rather than convincing your sister to forget about alex, or part of you befriending Olivia yourself. If you don't want him there, its totally avoidable already,.... its just an alternative route for those that want to do something different,... and I am totally happy with that.
That was a joke. Obviously the guy there is the guy the sister is after, and people need to remind themselves that the point of that quest line is to get the sis with a guy she wants to date, and in return you get Olivia. Or if you want the sister you can... but you won't get olivia, instead what you get is the sister being your gf.
I imagine these 2 paths are the main focus on the next update along with a new path, further development on the overall story and finally small developments to some events.
And seriously I hate the picky people who complain about everything and anything but I need to say this, I just hope it isn't boring. This last update was nothing short of boring. Too much grind for too little content... From the pics and what I imagine this update will bring I'm seeing more linear, not grinding story coming... It's a bet like zen. There needs to be balance between a bit of grind and progression. Too much progress and people will finish the update quickly and be bored, too much grind and people will get annoyed.
And from a 2-3 sentence thought I ended up here... Poh-ta-to
