This might sound controversial but

I simply can no longer bring myself to call couples in BL as "seme" and "uke". I used to do that in the early days of 2016 but it's just cringy nowadays. Also recently I stopped using terms as "top" and "bottom" since it's kinda demeaning to refer to them by whether they are in the giving and/or receiving end. So I decided to use "main character", "main lead", "male lead", "protagonist" and "love interest", "male counterpart", "deuteragonist". It may seem overkill but it feels more respectful to refer to characters this way.
