The plot of the series itself is kind of iffy in an extremely strongly cliched and "it has a great premise that it utterly wastes so that it can be so aggressively and predictably mediocre" sort of way, but it's enjoyable enough, especailly now that we're back to the MC and Senpai girl interacting (the fact that she's positive and supportive and he's being honest with her in return is a lot more than you can say for similar series).
Also I think that the translator is doing a very good job considering this is MTL, especially when you compare it to other MTL and single-person-TL-group works out there. I'd hate to see you drop this, especially if another group of equal or better quality doesn't come along.
Though honestly if we're now like 2 months out from the last chapter I'd start wondering if it was axed or is on hiatus or something. I can't think of many series that go less frequently than every other month unless the mangaka has some serious clout (Kiyohiko Azuma's success with Azumanga Daioh basically letting him publish Yotsuba&! on a schedule of "whenever inspiration strikes", for example)
EDIT: also forgot that the title spoiler of Gobubi being evolved into, apparently, a sexy goblin girl is kind of lame and disappointing, though I will reserve final judgement for when we actually get there. I kind of like cute little Gobubi, while senpai girl is present to be the eye candy. That said if Gobubi ends up looking like Gobuko from Peter Grill I won't exactly complain because Gobuko is best girl in that nonsense avalanche of a series and you can't convince me otherwise)
