Can you help me with "eren" hairstyle?

[DScounterGO]

Should I shorten the part of my hair marked in red when I want to grow the hairstyle in the photo? maybe it's better to grow this hair out? I'm having trouble tucking this hair behind my ears and I'm not even sure what I should do.

You want to buy a hair grip - their are lots of different styles exactly for this issue.

Let the hair grow longer, it will look pretty as soft tendrils framing your face as it grows or you can use some hair product and and clip it back if for a neater look.
