This drama mixes various topics and aspects of life perfectly. It starts as a high school drama, with lots of funny moments, struggles of student life and teen romance, how to find your own way, finding out what you like, what you love, experimenting with new things; and ends with making serious questions about adult and psychological issues. The casting is pretty good, main and side characters alike and the actors are really top-notch and versatile. They can be funny, lovable, goofy and can also carry out heavy drama at a very high standard. Moreover, the script and the characters are beautifully written, and side characters are not only in an insignificant comic-relief role, but certain characters are utilized later on in the show as a plot device as well as in an emotional drive, making them a feel more significant. The quality of the episodes only vary a little, every episode is entertaining and satisfying by itself, with the finaly one being the best episode in my opinion. It could be a stand-alone clip/movie as well and would feel very strong.
It is 100% worth watching the whole show and reaching the finale.

The questions the drama shows the viewer include:
- How do you find your own way as a teenager at school, at love, at your own family?
- What can you learn from another person culturally, emotionally, especially if they are totally different from you?
- How do you think about the future?
- What to do with your life after graduation?
- How to overcome the past? Is it even possible?
- What's the true meaning of life?
- And more....

What I can say is that this drama will:
- Make you smile
- Make you root for the couples' happiness
- Make you learn from their dynamics
- Lift up your soul to the Heaven, squeeze it and send it to the deepest parts of Hell

As for me, this BL should be placed on the same shelf as titles like Your Name Engraved Herein, I Feel You Linger in the Air, and I Told Sunset About You (ITSAY), which introduce you into real drama and heavy emotions in a nearly perfect way, with beautiful script, visuals, characters and actors. Although it is not as realistic as ITSAY, it really deals with serious topics not many BL dramas do. It's one of the really unique BLs ever created.

Personally, I have rewatched it already 3 times, at different stages of my life, whenever I felt like reliving some real or even sad emotions, or just to remind myself to believe again, and I enjoyed it every time I watched it, I feel its rewatch value is pretty high, but you tell me. :) I'm feeling a bit confused that its MDL rating is lower than its more action-packed counterpart HIStory3: Trapped, but I can accept that action and lighter BLs might be more popular.

You'll LOVE this show if you are empathic, enjoy details and can easily get engaged by heavy drama situations.
You'll NOT LOVE this show if you are only into fluffy, goofy, innocent, easy BLs.
