1. Their relationship starts out as purely platonic -people falling in love accidentally is one of my favorite tropes- and mostly consists Collin trying to help Loona open up & process her trauma, and why she treats people the way she does.

2. His dedication to helping her and, well, everyone he comes across eventually causes her to fall for him. “He could solve all of hells problems if only he was more confident.” “I’m an angel; helping people is my job. At least i thought it was…”

3. Collin realizes he’s in love with Loona after she calls him her guardian angel.

4. Eventually he ends up opening up to her about how much he hates being in hell, and how miserable he was with Cletus & Keenie, and how much he misses heaven despite its flaws, and that she’s the only things that makes it even remotely bearable. Of course; pouring his heart out like this is extremely emotionally taxing so he starts crying, and Loona holds him close and does her best to comfort him. “you’re one of the sweetest, kindest people I’ve ever met, if heaven is going to look for excuses to kick someone like you out; then heaven doesn’t deserve you.” After a bit he pulls himself together and says “I guess now you’re my guardian angel.”

5. They try to keep their relationship a secret at first, but Blitzø and M&M start to notice Loona’s behavior changing; she isn’t as aggressive, she smokes less, she engages more in conversations -if only a little-, she hasn’t complained about a hangover in a while so they assume she isn’t drinking as much. nobody starts working on themselves like this apropos of nothing; so they figure she’s cleaning herself up because she’s in love and wants her crush to like her back. “he makes me want to be a better person.” <- said after she fesses up about it.

6. When Collin is eventually let back into heaven; Loona makes him promise to visit every chance he gets. They have their first kiss right before Collin leaves.

7. They like to give each other gifts! Loona once gave Collin a leather jacket, which he now wears all the time.

8. After Collin goes back to heaven; Loona starts working out. Collin loves it. (Omg he’s just like me fr)

9. While in heaven, Collin gushes about Loona to basically everyone he knows, while leaving out the fact that she’s a hellhound. (Maybe deliberately, maybe not) The way he talks about her; they figure he’s dating a seraph. Boy, are they in for a shock when he does eventually tell them.
