This series is really really great, one of P'Aof's masterpiece, the actors, their acting, storyline, fanservice, etc. is so *chef kiss*.
You don't need some explicit scene to make a better BL series, all you need is a good execution of a story. And if some of you haven't watch this series, I recommend you to watch it because it's not only has a love story between the main character but it's also give us an incredible lesson about life. Also, if you're tired with some university things, then this series will be worth to watch, because the setting is more like nature thingy, and you'll be presented by beautiful scenery.
