Bandit's manga / #Possessive lover(30)

I love this manga, for both art and story honestly one of the best that I've read. But now coming back and re-reading it today. it honestly pissed me off A LOT. I hate that his Ex-Girlfriend is still a figure in the story and even feels the need to hang around as if nothing happened. Mainly hated the fact of the Ex-Girlfriend, she is so annoying it ruins me re-reading the story, I don't like that her cheating was pushed to "oh its okay I forgave her", and that she won't stop and leave the top alone. As well as during the serious moments of going back to his old home he started giggling, It just felt wrong. Or when they started going out after and when the uke felt upset by his bf's Ex-Girlfriend and the idea that he might be cheated on. While the seme was busy chilling with his Ex-Girlfriend and not thinking to talk much with the Uke.
