Hi, i didnt watch it yet because i am still hesitating to watch it. Close to this drama that i watched where they use mobile application is only Customized companion, it was BL and although i like BL dramas, this one was horrible. So then similar to using mobile app is only gaming. I had similar problem when i watched Love is better than immortality, so i wouldnt recommend this one. So with love story i would recommend Love and emperor (2020), I got you (2019), To get her (2019) and Love O2O (2016).
