Dang... I honestly never thought I was going to give a 1 mark to an anime. This one caught me by surprise.
I finished Domestig Girlfriend like two years ago or something like that, when I was on the wave of watching one shoujo anime per day. I must confess, it had me cringing and being like "WHAT THE HECK IS GOING ON?!" while watching it.... Like, in my opinion, there's no character development, and I'm just off with this "teacher-student romance drama" stuff so that's maybe one of the reasons that this anime never came to my liking.
If you like this kind of drama, go ahead and watch it, you may enjoy this. But was not for me. It's the perfect portrayal of a toxic love-triangle, with a plus of cringe from the step siblings trope.
Idk...I hope you enjoy it, i guess.
