this is probably the most rage inducing cheating bl manhwa that i've ever read to the point that i actually dropped this just so i could take care of my mental health. this manhwa single-handedly triggered all my rage and homicidal tendency, my ability to think sanely and made my brain a total wreck. i was punching my walls due to how bad this manhwa is. the mere thought of it makes me go mald even if i dropped this 3 years ago.
Try these!

Maybe My Hyung, and Here to Take My Revenge are more emotional reads out of those, but if you’re needing to get wrecked, try https://www.mangago.zone/read-manga/ways_of_parting/ it’s not really cheating, but the partner returns from being declared dead to find his love with someone else. (Not a spoiler, literally the promo summary)
