Imagine your OTP making flower bracelets/headdresses for each other in a field full of flowers (or any other setting, dependent on preference)
"I can't believe you convinced me to do this," Alec said sitting cross-legged on the picnic rug that they had laid out in a small hidden corner of Central Park.
"Flower crowns are pretty," Magnus said contentedly, as he wove two flowers together.
"And you're doing it wrong," Alec said calmly, reaching over and gently taking the flowers from Magnus and quickly and with agility wove the two flowers with the ones resting on his lap to form a crown.
"Where did you learn to do that?" Magnus asked, as Alec handed the crown back to him.
"Years of knot tying and weaving," Alec shrugged, as he took a slice of pizza from the box.
"I've never made one this good and I've made loads of these!" Magnus looked at the well-made crown and gently placed it on his head.
"Thank you," Alec said smiling at his boyfriend who was now trying to make another crown.
"Hmm what do you think?" Magnus asked, holding up a fraying crown, the stems sticking out.
"I think that I'm surprised that you're so crap at this," Alec mused taking the crown and gently unravelling it.
"Thank you," Magnus retorted sarcastically, watching carefully as Alec wove the flowers together.
"You're welcome," Alec smirked, as he gave the crown back to Magnus.
"This one is almost as beautiful as you," Magnus said, holding it up and gently placing it on Alec's head.
Alec smiled, striking a pose and Magnus smiled, watching him.
"I love you," Magnus said, putting a daisy behind Alec's ear.
Alec smiled, leant over and lightly kissed Magnus.
"Love you too."
