I’m not sure how well-known the Japanese cultural romantic context of the umbrella is to the internet at large, but for anyone who doesn’t know:
Drawing a symbol of an umbrella (a triangle with a line running down) and writing a name on either side of the umbrella handle is the equivalent to the western practice of writing two names within a heart and an arrow running through it—it’s a common way to symbolize “in luv 5ever like omg.”
You can stand under my umbrella….
But omg that’s a really cute fun fact <3
If we can ignore the fact that my handwriting is FREAKING ATROCIOUS (and slants up and to the right wtf?) this is what chirart was talking about above, and what it would look like for the two “couples” depicted. There’s a bunch of makers available on the web, too. The term for it is 相合傘, ai ai gasa, which just means “sharing an umbrella” but has a cute little word pun since ai also means love. (So you’ll also see people writing “love love” on the inside of the heart/umbrella sometimes.)
Japanese kids will often scribble these on chalkboards and stuff, and you usually draw the umbrella without lifting your pen.
let’s talk about yu and yosuke sharing an umbrella tho
