Novel with a little Self Help Book about appreciation of small things, slowing down, value of love and friendships

Hi, I’m looking for a present for a male 31 y/o friend. It should be in the direction of Notes on an nervous planet or Reasons to Live (Matt Haig) or The Well-Lived Life (Gladys McGarey). But I don’t want to gift a self help book, since this could be taken the wrong way. Is there a novel-like book that gives you a warm hug while reading it, teaching those things and self love in a more subtle way?

Thanks for your help!
