I have complaints about this, chief of which is that it doesn't feel much like a "love comedy," but the ending was just... ugh.
Open endings are usually either:
a) we got the axe, so their fight continues (just not in any way you'll see) or
2) HA! we got ya! this was just one long-ass ad for the books! now go buy them!
Either way, I loathe them.
Started good, ended bleh. Their fight continues AND you should go buy the LNs. 2/7. Does not go with rice.
