Imagine Person A of your OTP dragging Person B out of bed late at night, much to their annoyance, and dragging them up to the roof of their building. Person B protests the entire way and questions what they're doing, but when they reach the roof they find that Person A found out about a firework show happening that night and has set up a blanket and picnic basket. Touched, Person B kisses Person A and they sit together, watching the fireworks.
(More or less.)

Quite why Galvatron took so long to wake up was beyond Cyclonus.
He usually had such difficulty in keeping his sleep cycle running.
Carefully shaking Galvatron's shoulder strut Cyclonus tried to be as gentle as possible, he was not a morning bot.
Galvatron made dents in the berth he rested on as he clenched his hands into fists, snapping upright in bed he harshly batted Cyclonus away
"Just WHAT are you DOING?" he snarled harshly, his form bristling with sleepless aggression.
"Ah, Master" Cyclonus rubbed at his dented chest plate "I wanted to take you somewhere"
"And you felt it important enough to wake me up!?" Galvatron snapped
"I, ah" He cleared his intakes "Well there really isn't any other time to do so, unless we waited approximately five of Chaar's years"
"So?" was a huffed response.
"Please sir" Cyclonus pleaded taking Galvatrons hand in a protective and hopefully encouraging manner. Despite the way he acted Cyclonus knew Galvatron liked the simple, careful physical contact of something so simple.
"Hmm" He growled to himself "It better be quick"
Cyclonus always wondered if using Galvatrons attachment to him to get him to do various things was mean, but he always had Galvatrons best interest at spark when he did so, he shouldn't feel bad for it. Galvatron sluggishly dropped off the side of the berth, tightening his grip on Cyclonus's larger hand and allowing himself to be lead forward. Upon reaching the slightly cooler atmosphere of the corridors seemed to perk him up and he quickly demanded answers.
"Where are you taking me?" He quickly snapped.
"Surprise" He tried to brush off the question.
"No, I demand to know!" he refused to let it go.
"Sir, It's something special I want to share with you" rare excitement speckled his voice.
"Does it have to be kept a secret?" Galvatron whined.
"Don't you like surprises?" Cyclonus smiled.
"NO!" he snapped.
Cyclonus arrived at the doors to the Base's stairway and pushed it open, his long legs strode up the stairs swiftly but with a grumbling Galvatron in tow he kept them short. Easily pushing aside the entrance to the roof of the base Cyclonus eagerly pulled up Galvatron after him, his excitement was palpable as he tugged on his leaders arm to move him along the roof.

Galvatron had already spotted why Cyclonus had wanted to bring him up here and was staring too intently at the sky and allowing himself to be moved to where ever Cyclonus moved and then to be gently lowered down onto a blanket.
Above the stars that lazily glittered the dark sky were just hard to see specks as great misty lights danced and swirled, like long serpents courting each other and swirling in and out of each others coils, coloured a dull red parts of them flashed orange and yellow as each swirl twisted with carefree abandon.
Below them many of the Decepticons, if not all, had spilled out onto Chaars surface huddled up into groups, collections of rations in hand gazing upon the natural light show.
A dainty cube of energon was placed into Galvatrons now free hands, he managed to stop being mesmerised by the sky long enough to look down to his hands then back to Cyclonus who had sat down next to him with his own bit of fuel.
Smiling Galvatron shuffled closer to the Seeker pressing their bodies together tightly before leaning up to place a quick kiss upon his face plates before quickly returning his attention to the sky.
Cyclonus smiled and hugged him tighter.
