I've already learned how to use これ以上 when it means "beyond this" or further than this". But I'm confused as what it means in this particular context I came across.
I've been reading a sports manga. For context a girl cooks lunch for her friend once to motivate him to attend practice. The friend then adds another request on top of that, being for her buy him tea. The girl then says this.
What confuses me here is whether これ以上する suggests that she'll do this more in the future (cooking lunch and buying tea) OR she's only saying she'll do it this time without promising to do it more in the future (the original promise was only cooking lunch once).
