On second thought, this looks a bit complicated. This might take words.
(Warning for text wall and lots of caps!)

undyne: LOUD FRIENDS!!!!!!!! they’re always screaming! the two most determined people in the universe meet….. and have a hotdog eating contest
CHARA’S RELATIONSHIP WITH…:
sans: Don’t particularly get along. Paranoid of each other. They’re positive he hates them.
papyrus: Papyrus gives Chara ‘confidence classes’ and it’s awful but they’re very grateful anyway. Only other ‘friend.’ Fears he is annoyed by them.
toriel: …
frisk: Very close friend. Means a lot to them. Fears Frisk pities them.
asgore: …
flowey: …
alphys: Admires her, and is proud of her. Has never had a conversation with her. Fears Alphys looks down on them.
undyne: Idolizes Undyne to the end of the world. Fears Undyne hates them.
TORIEL’S RELATIONSHIP WITH…:
sans: Possible love-ish interest? Unclear. For now, good pun buddies!
papyrus: Thinks he is very sweet, and thinks highly of him (mostly due to Sans’ praise.)
chara: …
frisk: It’s their kid! Lots of love, lots of concern for this energy-buzzed kid.
asgore: …Friends. Ish. Kind of. Not really.
flowey: …
alphys: Held some contempt for her before, but is proud of her growth and the happiness she has found.
undyne: Thinks she is a positive role model and a nice friend. Don’t have much in common or talk often, but think highly of one another.
PAPYRUS’ RELATIONSHIP WITH…:
sans: HE SEEMS HAPPIER LATELY, BUT HE SEEMS JUST AS LAZY (IF ONLY TO GET ON HIS NERVES.) WANTS THE BEST FOR HIM.
chara: THIS CHILD IS CONFUSING AND ODD, BUT HE CAN’T HELP BUT NOTICE THEY SEEM… UNHAPPY. IF HE WANTS TO CLAIM THEIR FRIENDSHIP, HE MUST REMEDY THIS.
toriel: FINALLY REALIZED THEY’RE NOT A CLONE. THINKS VERY WELL OF HER. CALLED HER MOM ONCE.
frisk: EX-PARTNER(?), AND CURRENT BEST FRIEND!
asgore: KING FLUFFYBUNS. THAT’S IT.
flowey: CONFUSING FRIEND, SERIOUSLY WHAT ON EARTH IS GOING ON! SEEMS SAD LATELY, AND PAPYRUS WANTS TO HELP.
alphys: NICE, SMART, BAD TASTE IN ENTERTAINMENT. WONDERS WHY SHE AND SANS BROKE IT OFF.
undyne: ULTIMATE MENTOR! ULTIMATE FRIEND! YEAH!
SANS’ RELATIONSHIP WITH…:
chara: A mix of pity and contempt. He doesn’t care how ‘sad’ they are, though. A killer is a killer is a killer. Doesn’t excuse anything.
papyrus: Idolizes him beyond anything. The most precious thing to Sans in the world. (And his only living relative.)
toriel: Possible romance? Unclear. For now, though, she has 100 years worth of puns in her skull, and he’d really like to hear them.
frisk: Loves the kid. How could he not? Doesn’t mean he’s not terrified of them and their unexplainable powers.
asgore: A bit of an awkward relationship. Thinks he’s a nice guy, and he would have stayed that way had he not become king. Neutral. He does appreciate his unironically horrible taste in puns.
flowey: Knows nothing about him besides that the fact he killed everyone multiple times. Needs to be clipped.
alphys: It’s complicated.
undyne: Loves messing with her, and appreciates her watching out for Papyrus. Good person in his book.
ASGORE’S RELATIONSHIP WITH…:
sans: A bit depressing, assumes Sans and Toriel are together. Still, he is happy for them and tries to be a good friend. It’s uncomfortable for everyone but still very sweet.
papyrus: Admires his determination and goals! Reminds him a bit of an excited puppy. Get along well.
toriel: …Well, what do you think?
frisk: Sweet, merciful child. Frisk spends some weekends with him. Subconsciously adopted them.
chara: …
flowey: …
alphys: Is very happy for her! Thinks highly of her. Good friends, despite everything. Talk often.
undyne: Also adopted? It’s weird, but he loves his screaming fish child very much. So proud.
FLOWEY’S RELATIONSHIP WITH…:
sans: Liar.
papyrus: Idiot. Deserves better.
toriel: …
frisk: Weirdo.
asgore: …
chara: …
alphys: This is your fault.
undyne: Whatever.
ALPHYS’ RELATIONSHIP WITH…:
sans: …Complicated.
papyrus: He’s very, very sweet, and kind, and incredibly overwhelming in every way.
toriel: …Avoids her. Respects her, still.
frisk: ‘Precious cinnamon roll, too good for this world, too pure.’ And she’s ruining them with anime.
asgore: Friend, old boss, old romantic interest? Whatever, they’re really good friends. She doesn’t fear that he’s judgmental like everyone else.
flowey: …
chara: Wary of them. All they know of them is the tapes. They’ve never had a real conversation otherwise to prove her wrong.
undyne: I wan’t you to take a wild guess.
UNDYNE’S RELATIONSHIP WITH…:
sans: Irritating, but a good person! A secret nerd, too, because both Alphys and Papyrus slipped information about his weird love of science and tinkering. Shouldn’t he and Alphys be friends?
papyrus: ULTIMATE KNUCKLEHEAD! They can and will noogie the skeleton!
toriel: Thinks she’s nice, if not a bit stern! Takes good care of everyone, though, and is a real motherly type. Respect.
frisk: NGAAAAAAAAAAAAAAAAAAH!
asgore: Dad that doubles as a best friend. So cool. Such a wimp.
flowey: …Weird.
alphys: What do you think?
chara: Pity, distaste, and the overwhelming urge to just - get the kid some therapy, or SOMETHING.
Welcome to tumblr! Are you on here through the Undernet or Internet?
CHARA: * This is as ‘surface’ as it gets. We live in the suburbs.CHARA: * Also, I guess Undernet is the new social media app on the surface. I’m sure Alphys has Tumblr, too, though.
