Both seme and uke been in a relationship before, but they're not a cheater or some kind of "fuckboy" type of characters
There's no cheating cause the ML is DOWN BAD BAD BAD for MC. It's a healing novel, so it's more focused about how the MC overcome his trauma and more about human relationship, about forgiving and try to be a better human being. (You can give it a try if u want some "healing novel" that more focused on how people try to learn from their past selves and try to accepting, self-love and etc)
No love triangle ofc, but the MC (shinwoo) ex probably showed in some of chapters but they already clear their issues so it's a mature relationship one, no drama for love triangle or whatsoever~
This was such a good chapter. Uke finally got courage and took that step we all have been waiting for. Ik it's not easy to open up and it will be a long process for him but I'm satisfied with him taking tiny steps
