There's nothing wrong with being heartbroken over that..... but he is still obligated to find a new partner because he has a main cast role in Magic Lover series (it's a work thing).

However, just to clarify though. Your Third was still filming up until very recently (like last week but I can't remember the date specifically right now). The character Payu (which is JT/JJay's character) should have appeared long ago if following the novel storyline but is only just appearing in final episode which means Ohm did not have a partner back when they were filming those scenes. They only added him now because the final episode has only just been filmed. So no he didn't always already have a new partner.

The description is wrong. Sib is the sibling that Jam works for and the one that swooped in and stole the spotlight (that love interest is Peemai). Song is just another brother that's Sarm's twin. The novel's description is same but doesn't say the brother's name so whoever wrote it added the wrong name here.
