I recommend the REACH Spicemint scent.

I tend to be conscious about bad breath, so I always keep mouthwash on hand. I remember receiving this as a gift; it has a refreshing mint scent like typical mouthwashes, but I recommend it because the scent seems to last quite a while. I'm not sure if they are still collaborating with Kakao, but I like that it has cute Kakao characters on it! I pour a full cup into the cap, rinse my mouth for about 10 seconds, and then rinse with water again. They say you don't need to rinse, but I feel a bit uneasy about it. Though, I do think it might be more effective if you don't rinse. I recommend it.
