After the MM episode.. this is my take on DV.. asking him why.
Why would he leave Sachi alone in that party? I could understand if it was some other time but it is the first time they are going as a couple AND the most important thing, she doesn't know anyone there. I expected a little more sensibility from him, he who claims to have a Sachi radar đ It was not a business party where he needed to meet client or you know, discuss business matters. I thought the point was for her to meet his friends?đ She met like 2 and then he went off to meet the rest. If he thought it wasn't the right time to introduce her to everyone (friends + friends' family) he shouldn't have brought her in the first place.
And I don't know why but I sort of wished he introduced her to his mom as well. I know he might've wanted to introduce them at a nice place or what not. But I just felt weird he didn't introduced Sachi and drop hints about what he wants since he's so sure his mom approves.
So, the dance, I think the whole Anky (Panky.. đ ) business gets on our nerves because she has feelings for DV, otherwise it wouldn't matter. But DV doesn't know (and guys in dramas never know about the scheming bffs they have). Personally, I understand how Sachi became uncomfortable with the dance. She is not used to it. DV should've been aware of this. But I didn't see DV behaving inappropriately (even if I don't like it, personally).
Sometimes I think I just expect too much from DV since he has been this perfect guy so far. But most of these things seem pretty common. As for Sachi, she shouldn't run like that. I would hate for her to be a crying a river on how DV doesn't love her or is getting engaged. She should know better.
