Yeah I am also not at all a fan of bringing "trending" internet lingo like simp into the translations. Not only is it highly transient (somebody reading this in a year might have never heard the term - even now many will still not know it), it looks dumb. Reminds me of watching twitch streams with high viewer counts where everything in chat is just dumb copy pasta, kekw and pepelaugh. It can have its place when actually portraying a character that talks that way, but in an otherwise normal conversation like the one here it's a foreign object and feels downright wrong.
Aside from that, fun chapter featuring my favourite girl, so thanks for that.
