I'm totally rooting for Dohwa and Suae to get together. They have such an easygoing vibe, and he just gets her. He cares about her a lot and they have a ton of fun together. Plus, Suae gets him and is super kind to him. Their connection feels real. The tension, the one-sided crush, and Dohwa being willing to step back for her sake – it's all so interesting! On the other hand, Eunhyuk seems to be using Suae for emotional support because of his past, taking advantage of how understanding she is. It's like that one webtoon "True Beauty" – everyone loved the second lead (Seojun) way more than the main guy (Suho). 
 
Second leads always seem to bring more flavor to the story.
