Sameee I first I was rooting for theo, but theo and the other princess has insane chemistry.
Theo has nothing but pity and empathy for Lina. They could never be. The basis of a relationship must be mutual respect. I don't believe that's possible with Theo treating Lina like an inexperienced underling to mentor through the art of life. It's clear he doesn't feel romantic feelings for Lina. There's none of that blushing or surprise of the mundane that he shows with our MC.

One of the reason why i dropped this. She loved her past bf in all her life and was devasted by his death, leading to one of the reason for revenge against the devil but now after reincarnating as devils child she suddenly being happy and chumy with devil family, and now even after meeting her past lover again, she feels nothing but melancholy/nostalgia and she's even falling for someone else...... Did she even really loved her past BF? If the past BF cheated or betrayed her then it would have been different and understandable but the past BF loved her in all life (even in this life, when she's in different body) plus he died protecting her in all life, but she...... how can she just easily move on.
The more i see her past with her past bf and the treatment, the more i hate MC and the whole story which already doesn't make much sense with lot of plot holes. The Past BF deserve better.
i still want her past bf to be the ml even tho it's obvious it's theo ☹☹
