One if them is trying to "grow" out of a Class S relationship, because you know, in Japanese society, it's the right thing to do. The other doesn't see a need to grow up out of it and wants things to stay that way forever. That's obvious why she would make a childish threat of killing herself.
Anyway, it's a story, it doesn't have to be tied to reality (suicide threats are serious business). The author used it as shock value, because it's just a chapter long and they needed a way to make Miharu realize that growing up out of this Class S relationship doesn't necessarily mean destroying it, but can also mean "adding more and more to it" and take it to the next level, yes ?
