I don't read Japanese so bear with me, it ended the last 2 episodes with the MC meeting with mone's dad for the first time, and then the MC and mone talking about the moments they had together, but they ended as a couple...
but wait there is more! an epilogue with the same style as the .5 episodes (so as an extra), and it shows the future, and it is a harem ending in the epilogue (rich girl, catgirl, devil girl that is not shown up yet, sport girl, and mone)
