Is it right to treat this area to create an in-mode V line?

I got In-Mode because I had a lot of fat on my face compared to my body fat and it was sagging.
 I also tried Shrink 300 to improve my elasticity.
 The price is 190,000 including VAT including Inmode FX Full Fee Shrink 300. It's
 
like a one-person clinic. Before the procedure, the director asked me about the area I wanted to focus on, and I said I wanted to have a V-line.
 However, although it is done on the entire face, it is mainly done under the chin...
 After the procedure, the location of the bruise is almost under the chin. As far as I know, this area is
 known to be a double chin area. Double chin fat is not a concern and I received consultation at another hospital, but the double chin is almost there.
 There isn't one, so I wonder why I focused on this...
 It's my first time making a V-line, so I wonder if this is the part I should do in the first place, and I
 feel like I wasted money for no reason.
 Is it right to do this?
 If you look at the picture, you want to tighten the flesh in the area marked with a blue circle when viewed from the front. As
 you can see in the second picture, it's only tightened like that under the chin, right?
 
Question
 1. When you say you want a V-line, is it common to do that area?
 2. If I am trying to lose weight in the area shown in the photo, which part should I ask for?
