Don't have a pixiv account so I had to muck about a bit to create the source link, apologies if it ended up wrong.
On another note, as with the other images in this series the dialogue is mostly from the official bond interactions/whatchamacallems. Here's a copy-paste of a translation from https://fategrandorder.fandom.com/wiki/Sub:Boudica/Dialogue:
"I don't really hate people like you. Aa..... no, no. Things like this must be conveyed properly else I'll end up regretting it later. (note: the text from this image doesn't match up that well after this point) I like you. As a Master, and as a person, I really like you."
