Kabukichou bad trip!

Hi everyone,
I’m trying to find a BL manga (Japanese, black-and-white) where both main characters are ex-boyfriends. At the start, they’ve already broken up and have unresolved feelings—they’re awkward or hostile toward each other at first. As the story progresses, they realize they still love each other and eventually get back together.
What I remember:
They are exes with each other, not one-sided
There is tension / bickering / resentment at the beginning
Strong rekindled romance theme
Black-and-white manga (not a colored manhwa)
Possibly set in a workplace like a café or restaurant (not 100% sure)
If anyone recognizes this or has similar recommendations, I’d really appreciate the help. Thank you!

I saw a tag that says childhood friends promosed.to.marry each other. Where can I find that? ( ̄へ ̄)
Hehe it seems nc.
