The last scene has one of these after another. Dandy decides against taking her to the Registration Office despite her worrying about all the money he spent tracking her down.

By the end, Meow feels like he's become much closer with his father, and when he's leaving he gives a heartwarming goodbye to him, his father saying he doesn't mind that Meow choose to explore the universe instead of becoming a metalworker.

Episode 11: I'm Never Remembering You, Baby
Subtle example, but Bea is prominently shown being concerned for Gel's well-being. Bringing him tea and asking him to take breaks, actually stopping being a slob for once and trying his best as a replacement, and not abandoning him by evacuating when Gel's going crazy in the end. This is especially noticeable when you remember Dandy didn't really give a shit when Meow seemed sick.

In his own... let's say special way, Dandy proving Freckles is beautiful in her own way... by pointing out she has a rockin' booty.
During graduation at the end of the episode, Freckles tells Dandy she has a gift for him. She kisses his cheek, Dandy himself taken aback by the gesture. Not to mention that that we're told a Cliponian's head flower sprouts when they fall in love, and Freckles flower sprouts as she watches Dandy and his crew fly away.

Episode 23: Lovers are Trendy, Baby
The majority of the episode is peppered with Dandy and Scarlet having cute little moments together.
It's immediately followed by Dandy being his sleazy self, but when Scarlet walks up to Dandy in her one-piece swimsuit, does Dandy comment on her breasts, hips, legs, or ass? No.
Dandy: "I like your hair down like that. It looks... really good."
It's worth noting that after Dandy says this, Scarlet keeps her hair down even after they leave the beach on their subsequent dates, only putting it back up after the termination of their contract. But not before she goes to the bar to wait for Dandy one last time.
Dandy and Scarlet finding out they have similar movie tastes, and the two begin fangasming over their favorite action hero together.

The fact that Catherine meant a lot to Dandy, even after all those years.

Catherine decided to get together with Paul ten years ago because she couldn't stand the thought of him being lost as to how warping worked and because she knew that Dandy would be smart enough to figure it out on his own, which speaks volumes about how much confidence she had in him despite everything.
Episode 26: The Never-Ending Dandy, Baby
QT, Meow, Scarlet and Honey all taking the Aloha-Oe to rescue Dandy from the Gogol Empire, suicide mission be damned.
With the Gogol Empire's superweapon primed, Dandy prepares to take Gel's ship and destroy it, and it's likely to be a one-way trip. When his friends protest, Dandy tells them that he doesn't want them having to risk their lives for him again, before taking off.
Dr. Gel saying that he will be honored if Dandy pilots his ship in order to save the universe, that's very sweet considering how long he wanted to capture Dandy in the past, plus with the powerful music in the background.
The first thing Dandy asks QT when he briefly remembers that he's in a new universe is "You are still you, right?"
