The main reason I was interested in this drama was Ren, he is unbelievably attractive and his acting was pretty good as well. I don't really have any remarks on it. Kazuma's acting was a lot more awkward, escpecially because of his facial expressions. The rest of the characters were decent and provided more of a side role. I did like the French guy at the end, his acting was noticably the best and he was really handsome as well. Overall, this is a short BL with sweet moments and a decently interesting story. I recommend to watch.

I do want to add that I found this BL to be a bit more realistic than other BLs, where one's reputation because of their sexuality could change and how people can deal with it in a realistic way.
