Nope. It's actually complete already. And the ending was just right too~! Actually, more than 'just right,' I find it perfect. XDD It's cute. You should read it! :>
[EDIT] Joookeee.. I reread your reply again and noted you actually read it already. lol But, really, afaik, it should be complete. Idk with online manga ver though...? Maybe the translators just stopped translating...? Not sure.
