It's cute and I love the art but no, I don't like the fact that he ended up with Seo-woo, he was a coward and asked his brother to approach him, just this is not right. it's not rare to fell in love when try spend so much time together and from he beginning Jae-Woo was the one who helped him with his fear and even with his bullies.
It's my personal opinion but if he need someone else to approach him and start the relationship then it's a big no for me. It's ok to ask for help but he just used his brother and took him away in the end.
