how about the questions 2, 18,26,29 and 30 ? ( if you're still doing them :3 )
2: Who sleeps in the other’s lap?
It varies sometimes, but generally it’s Gladion. It also doesn’t help that Sun likes to pet his hair.
18: Who’s the first one to admit they have feelings for the other?
Gladion was the first one to realise that he had feelings for Sun, but Sun was the one who first admitted it (by showing a note into Gladion’s hands and running away)
26: Who takes a selfie when the other one falls asleep on their shoulder?
Sun does sometimes, since he likes to take photos for memories. Gladion has his lock screen as a picture of Sun sleeping on his shoulder though.
29: Which one holds the umbrella over both of them when it rains?
Gladion does this because he wants to keep the rain off Sun as much as possible, even if he ends up not completely dry.
30: If your OTP went on vacation, where would they go and what would they do? Who would take the pictures?
They’d travel to Kalos and do some battling together. They do go visit tourist sites, and its Sun who usually takes photos of the landscape but thinks he sneaks some photos of Gladion too. Gladion notices, he doesn’t really mind/care.
