This was a typical cliché-like drama matched with non-cliché-like elements. I watched this as a gap filler because of its short length (and the kisses). If you're like me, falling for that cliché part (though never admitting it haha) and curious about the other parts, give it a try!
There's the typical cold, rich male CEO with a kinda dumb, childish, poor girl... at least that's what it quite seemed like at the very beginning. Buuut let me come to those non-cliché parts, because that's what made this romcom special to me:
- the pain exchange was an interesting aspect to me. haven't seen that in a drama before. ML's acting was HILARIOUS, I laughed my ass off when he was dying because of period cramps hahaha
- no cringey "girl chasing the man" part before they start dating. both fell in love gradually at the same time, also to me they didn't have that "meant-to-be" vibe right from the start which would've made that drama more predictable as it already was anyways
- generally, FL didn't turn out that dumb as probably expected (to me)
- the MMA part. well yes, but also no haha, Ke SiYi's character didn't match a MMA fighter AT ALL (I feel like I just needed to stress that:(), but the other girls did, and I liked the story of their fight club in general
- FL's patchwork family
- this was literally me the first time seeing skinny jeans in a cdrama lol. don't get me wrong, I love the asian baggy jeans look, but I really liked the FL's plain outfits, simple but suitable for her :)
- THE KISSES (btw the first couple is dating in real life COULD MY DRAMA COUPLE'S HEART BE HAPPIER I guess no ). their on-screen chemistry was also soo good.

I don't want to make this too long, so here's just another few points I want to mention:
- the sound effects fitted PERFECTLY tho. usually I hate them because they go on my nerve so bad, but here, it really did what it should and made the whole thing funnier
- this was probably the second couple with the least screentime I have ever seen in a drama. it was even too little to decide weather they had chemistry or not :( also meaning that they didn't really have a story... kinda sad if you're like me, always falling for the second couple :(

Last: I was kinda surprised when I saw the rating, I seriously expected it to be higher. I mean come on, I'm pretty sure this drama's first-hand intention was to be entertaining, not to have a life-changing deep "giving us sth to think about" plot. Yes, they were plot holes, yes, we all might've had some "whyyyy tf is she doing that" moments, but come on, our lives have plot holes too lol, and if everyone acted rationally when being in love, there would be no dramas in this world ;)
