While I would love to give Spawn Astarion a portrait, you can get presents for some of your companions, though they are less casual than Shart's flower & statue. Astarion is very grateful to be given the "The Necromancy of Thay" It's maybe not a super cute classical romancy present, but gifting someone the tools to understand their condition better, and give them an edge in the fight against their old master is quite a nice gift. Same goes for the "Annals of Karsus" which Gale desperately wants and the Orphic Hammer for Lae'zel. The recent addition of text options to give the egg into her care make this quest feel like you are doing something for her too.
No objections to more chances to be nice to my character's partner and friends but breaking into secret vaults to steal books or a hammer of legend for them, are perfect "dates" or bonding experiences. =D Heist dates are the best dates.
