His family cafe might be struggling at the moment given the current circumstances, so with that as a consideration I would understand if he was struggling to splash out on a gift. He might have something planned for when he sees her, so I'll reserve any kind of opinion on that for now. I personally would be so happy with a bouquet of flowers from my girlfriend, but that's because my love language is more so about small gestures and reassurance, than gifts. I do find it a bit odd that the mention of his gift was such an afterthought, though.
But yeah, with Lucille... I almost feel like she doesn't belong in a relationship? That might sound weird, and I understand that it's her first relationship so maybe that plays into it, but she seems so unnatural. I have no problem with her relationship, but I struggle to ever watch anything where she's with Michael because everything feels so stiff and awkward. She does seem a lot more comfortable expressing love towards her family. I think, for me, she'll always just be one of those people I can't ever picture in a romantic or... otherwise setting. I've only ever seen her look relaxed or like herself when she's with her family. Also, in videos where they've kissed (I swear I've seen them kiss in videos??) it's been such an unpleasant viewing experience. I don't exactly want to see that on camera either way but when it's another couple I don't visibly cringe like I do when it's them.
