Don't put your money on it. The first series has been a train wreck that should of been only 13 episodes. They drew it out and looking at the spoilers for 23 and 24 they're drawing it out till 24.
The game has an ending for every girl and the various heroines manga has a book for every girl. Hell theres even a light novel whereKouichi chooses Yuumi, Kai ends up with Mitsuki and Mao is left alone
So even with a TV series ending it's pretty much a "take your pick".
