It's a harem story with a happy ending, so yeah, he get's together with Tata (and the others) eventually, but I didn't read it all yet, so I don't know, when he finally gets together with the first girl, will take a while, probably. Just one thing is uncertain, since there's a deviation between Web Novel and Light Novel. In the WN his childhood friend, Aria, stays with the hero, while in the LN it's portayed as a misunderstanding and Wazu gets her, too. At least as far as I know. This new adaption seems to follow the LN plot, so he should get the full harem course eventually.
