Ieva and Rokas are both getting a bit chunkier. Maybe they feel they can relax now that they have found their life partner.
And I agree, Ieva seems so full of herself. I do see it as an achievement that she has found a man and a group of friends, this is something she was struggling with for years, giggling helplessly around men, never really belonging anywhere even though she spent her whole life in Klaipeda. But she seems a bit too smug. Sure, she moved into her little apartment (I remember people on GG would say she had to move out for years, she was too old to live at home like she did as a child), but she is still living this fairy tale life of cooking meals and running errands, she still doesn't take on full adult responsibility. And now she wants to jump straight into marriage. She may be surprised that relationships are hard work, too, and that she may not have the skills for it because she has never stuck with anything that was important to her in her life, she was always lazy and let it slide.
I also miss seeing love and happiness on Ieva's face. We cannot look inside her, but this is the guy she wants to marry and they are still in the stage where everything is blissful, and I think it should show on her face more. She seems satisfied and complacent but not full of life and emotion.
