looking for a manga

all i could remember was there was a family dinner scene, they were all eating at the table and one brother came out as gay, then another brother came out as gay, so the mother look at the last guy and ask "how about you?" and he said "im into girls" and the mother was like ok. gosh i swear ive read this beforeeeeee but i can't remember where or whether its BL or straight. although im sure it's a manga. thank you!
