Looking for manga with a character who helps the main couple get together

[TrustyCactus79]

So basically I'm looking for a character who is helping the main couple get together completely intentionally. They can be the protagonist or not as long as their goal is helping the "main couple" and they appear fairly frequently. If anyone has any recommendations, I'd appreciate it!
