I liked this beginning.
Although I must say that Lois made me a little desperate because, despite the initial shock, she continues to underestimate Luthor, since he loves her he won't hurt her. Doesn't she realize that she might not be physically harmed but that everyone around her would be in danger? Luthor has no scruples and if to obtain it he must kill everyone around her, he will do so without hesitation. The explosion of the planet is the biggest test he has (until he finds out about the kryptonite cage).
I hope this is well written. If something is not understood... please correct me.
