I always end on a proposal ending as it is a "happy" ending but also open ended so great way to end a book.
Coach:
You sat on a suitcase, Coach standing before a table with a map laid over it. Red lines were drawn on to illustrate the best route. Or so he hopes. All this risk makes him anxious.
"Wanna sit?"
Coach looked as you motioned to the suitcase beneath you. "Nah. You sit."
"What kinda place doesn't have a chair?"
Coach shrugged. Honestly his brain is blank, or maybe not, not that he could tell right now. So how this slipped out he has no idea; "When we get out, I think be great if we got married."
"How did we go from needing chairs to marriage?"
"Not a single clue."
"... right."
"So you ignoring the question an indirect no or?"
A chuckle slipped out of you. Got up, walked over, then slid arms around his neck. "You didn't ask."
"Right, my mistake," Coach chuckled, putting his hands on your hips, "Will you marry me?"
"Yes. A million times yes."
A soft kiss got shared, two smiles growing cartoonishly big, then he joked; "Now that you got off I WILL be taking my turn to sit."
Rochelle:
It wasn't how either planned it.
Zombies on your heels, panting, thighs burning, shouting. You aimed to a restaurant, shouting "There!".
Both raced through the place, to the back. Minds weren't working, simply a fight or flight happening.
Both slammed a door shut, you motioning to a storage rack and shouting 'move it in front!'. Rochelle was quickly aside the furniture, pushing as fast she could, a scream of desperation. Your body kept being forced forward with each pound to the door, each gurgle sending an icy cold shiver down your body.
Once two storage racks was in front of the door Rochelle hurried to you, hugging you tight; "What do we do?"
Maybe the worst place to have come run to. Low on ammo, no window to escape from, the only exit bombarded with beings so determined to tear your body apart.
"If we make it..." your breathe was trying to steady, "We should get married."
"Huh? Now?!"
"When else?!"
"... fair. If we don't?"
"Then... we go out together so... that's good."
"Our definitions seem different on 'good' and I rather you survive even if without me, but yes. Yes to both plans. I had plenty of time to plan out a wedding already so it will be quick work to arrange it all."
A coo slipped out of you, "You thought about it?"
"Of course." BAM! The racks collapsed, the door bursting open. "But that will be a talk for later!" Both raise your weapons, deep breathe in, "I didn't plan this all for nothing so you better survive!"
Ellis:
It was a spur of the moment thing. Things were exploding, the second horde was racing around, bullets flying. The chances of dying are so high, growing bigger and bigger each passing day, and something has been nagging at him each day now.
"Hey!" he called over the loudness.
"What?!"
"Wanna marry me?!"
Silence. Somehow that silence was louder than the chaos surrounding him. Before you could answer he ran away, yelling,
"Think about it! Gotta help someone over there!"
He did not. He got scared. But halfway to running to this random new location he realized maybe if he gives you too long to think you will go with 'no'. So many thoughts that it made him less focused.
Being less focused means death. Luckily he snapped out of it, by your help. Suddenly you were in front of him, snatching his collar; "Yes!" smashed lips to his then pulled away, pushing him then lifting his weapon, "Now focus!"
Once the zombies were done the first thing he did was run to you, smash into a hug then twirled, giggling and rambling on and on about all his ideas, who he will invite, where it can be held, etc. So many kisses, not one long one, no. Few kisses on your lips, your cheeks, your nose, then your lips again.
Nick:
'I am NEVER marrying again!' was the promise Nick made himself right after signing the divorce papers with that bitch.
So why does he have a ring in his pocket, for you, to symbolize wanting to spend the rest of this shitty life with you?!
You know Nick enough to know something's wrong. To tell the difference between his usual asshole behaviour with 'something is bothering me but I never learned how to talk about feelings' behaviour. Sometimes you just have to let him come to you on his own terms, other times if it takes too long or progresses to too much mean behaviour have to argue to get it out of him. Not a good trait of him but not as if these are the times to work on red flags.
You waited two days; His behaviour kept being cold, remarks that aren't teasing or sarcasm but just mean now. So you finally walked up to him as he sat on the ground, checking his gun, only to have it kicked aside.
"What's your problem?!"
But looking up he saw your hands on your hips, glaring down, "What's YOURS?! I'm not your stress ball to abuse, I'm your partner."
"I wasn't-"
"Should I repeat all you have been saying?! I'm your partner so talk to me. There's no shame in needing to talk. This isn't the 19th century anymore!"
"I fucking know that!" Nick got up, not liking being talked down to, literal and figuratively, "I'm just thinking about something."
"Then share it so we can figure it out together."
"No!" This kept going back and forth. You wanting to help your boyfriend, and stop his shitty behaviour for the good of all, and him wanting to have a proper proposal plan. But all this stress was getting to him.
"Fine!" his hand dug into his pocket, "You wanna know what's been on my mind?" You got a shock when your boyfriend suddenly fell. To one knee. And a box held out, opened to show a ring.
"What the-" Your brain might have just stopped. All did. "... is that blood on it?"
"Ignore that part."
"Okay."
Nick's heart was beating fast, blood rushing, "O-okay to the proposal or the ignoring it?"
"Ignoring." "Oh..." "Yes to the proposal!" "Oh!"
Nick's worried, nervous expression changed to a grin, jumping up to cup your face and give you a deep kiss.
"I can be a shitty boyfriend at times, but I'll be a great husband."
