The romance in this is pretty cheesy and simple, relying on Cordelia getting embarrassed time after time, but the author has made it work really well. In fact my initial suspicions about having two isekaied characters have been removed by the writing. Since the two MCs here can relate to each other and thus keep the "it's just a game world" mentality going on much stronger than a lonely isekaied MC, I always fear the world won't feel like much. But it's working well here. It's naturally slowing down the romance, as they both could feel like it would be a mere game romance, happening between their avatars, but it's quite enjoyable as it is. Or maybe it's enjoyable precisely because of that twist: it's not a priority, so if it still happens, there must be something to it.
