how would the LI's comfort/help vesper if they were having an overall bad day? i feel like i've been having a whole bad month ..
Francesco
He'll take them to that bakery in the corner they both love for breakfast, buy them bouquets of flowers, and shower them in kisses. He feels awful about Vesper having a bad time, so he wants to do everything he can to make it go away quickly.
Keir
He'll do what he can to help if Vesper tells him what he can do to help, but the biggest thing he can do is to listen and give headpats and reassurance that bad times suck, but they're not forever.
Oleander
This man is not great at comforting folks so hugs and sincere words are not really on the table. But maybe he takes Vesper out for a fun date, and maybe during casual conversation he hears about something he can do to help, and maybe the next day Vesper learns that he's done that thing to help.
Cirrus
Instead of doing a lot of things himself, he would encourage self-care and taking care of their body (eating a healthy meal, taking a warm baths with special herbs, going for an impromptu workout, etc).
Of course, if they wanted someone to talk to, he would be there - but he believes in better results if the problem is tackled a bit more directly.
