Nov end honeymoon island recommendation

Hello beautiful people, I will be going for my honeymoon between nov last week-dec first week. We wanted to do a very short honeymoon (about 6-7 days) and cover Bangkok + 1 island.

My fiancé and I decided on Koh Samui and thank god that i read this sub, i realised it’s a bad time to go there (rains). We plan to stay 2 days in Bangkok - transfer to an island for 2 days and come back to Bangkok for the next 2 days.

I am very confused about the other island. My vibe: RELAX, great massage, great food, pristine beach. Low party options would be great as I’m not a very big party person. I enjoy peace and quiet. Do you think Koh Kood fits the bill? PLEASE HELP YOUR GIRL 🥲
