Osekkai Joshi, Koi o Suru

Here’s a natural, fluent English translation that keeps the rom-com vibe intact:
Chitose Gamagori is a meddlesome girl who can’t stop meddling in other people’s love lives.One day, her best friend Nagisa asks her to deliver a love letter to Makita, a boy from the next class.But instead, Makita turns his attention right to her!
“N-No way! Nagisa’s way cuter! There’s no way someone like me… it’s impossible!!”
A sweet-and-sour youth romantic comedy full of flusters, starring a well-meaning best friend who suddenly finds herself at the center of the drama!
