have a feeling they became lovers! feel like it was heavily implied(he was even saying how if he was going to die, he would have wanted to be w her) and in the final chapter when huisu meets everyone again, u can see minwoo and rina in the tgt in the bg!!
For anyone who wants to have a breath of fresh air after the latest chapter of Jinx, I want to prescribe you this story, "Our Sunny Days"
Something healthy for the heart
