I personally think she is fine even as a love interest, and I think they broke off the engagement in agreement for both parties—with good terms. But looking at the development of their expression, the romance probably won't be developed in early stage like this.
I mean I already saw a character like Julia in "Villain's Will to Survive" which is a very much more worse and annoying that any other fiance/ex in the whole manhwa universe. So to me, this Jin Soyeon is fine lmaooo

Haha, yes I'm aware that you don't want it now, because me too, I feel the same, early romance is just no good when he barely keep himself together in the whole Heir fight—aka weak by his clan's successor basis.
Which is why I tried to reassure you that it probably won't happen this early. Though I'm not sure myself since I've been betrayed by countless author already let's just keep gaslighting ourself
I hope the ex fiancee remains just as that
I don't want romance in this manhwa especially not at this stage and ESPECIALLY not an ex
Please
