Hi all, I need to find this specific manga if anyone knows.

All I remember is:

• the protagonist is still teenage and his/ her (forgot the gender) family owns a shop possibly related to food (i think it was a bento/catering?)
• the protagonist's mother is bestfriend with the wife of local yakuza gang
• the teenage often do deliveries to the yakuza family to deliver items from the mother to her bestfriend, one I remember strongly in one of the scene is cloth materials to make the kimono
• one day someone ruins the shop, and the yakuza gang retaliates due to the friendship between the two family

other than that I don't remember the genre or anything else.
the manga could probably 2-4 years back, but not that old. because it doesn't have that old-style drawing.

thank you ^^

i think it " tight rope" by natsume isaku, a SA/YA manga
