If you want something chill and refreshing, this is the series for you! If you want some drama then I would advise you to come back to it another time.
By now, you've probably read many reviews saying how nice and wonderful this drama is and in all honesty I wholly agree! Now I would advise, don't go into this expecting something phenomenal. It's not something new and never been done before and it certainly won't be the last. People who've read all the reviews and started watching it while riding the hype train will certainly feel very underwhelmed. This series isn't doing anything out of this world. Just take it as it is with the only expectation being that it has 'little to no drama' kinda mindset.
Now my personal reason for liking this series so much. I've watched a lot of drama in my life, more than I can remember to list them all on here, but this series was just nice. While being so unproblematic unlike real life, it was still so realistic. The plot is pretty mundane in that it's a slice-of-life romance series of a group of friends in high school, following their journey as they grow up. That's it. Nothing crazy. But what I love so much about it is that they take certain scenarios that you've probably seen countless times in other romance series and, wait for it... have the couples communicate!! Wild. But no, seriously. Nothing in this series will make you feel frustrated and make you want to rip your hair out. You can enjoy it for being unrealistically realistic while feeling happy inside thinking that somewhere in the world, there is a couple out there who is as much of a green flag as the couple in this "drama". It's a slice-of-life so you should definitely be aware that this series is not a minute by minute take on the character's life but rather the most eventful. It's not a deep dive into every conversation that they ever had so having mainly chill moments is also plausible. From watching this I certainly found myself kicking my feet a little at cute moments between the characters and felt like I really missed out on certain aspects of my own personal life. If anyone else here reads mangas, it really reminds me of one of my fav. also similarly chill/fluffy manga "RERE Hello". I felt like the cast all acted their part well and the comedy was casual but still funny. Overall, I just liked it because they did an already done trope well. Also, one gripe that I have about many drama is that they usually don't know how to end a series, one issue that this series didn't have problem with. I felt like they ended it at the perfect time and I wouldn't have had it any other way. I would 100% recommend this to anyone who is tired of/or just wants a break from gut wrenching sad dramas. Take it as it is and just enjoy!
