EXPLORING CDRAMAS. NEED RECOMMENDATIONS FOR MODERN CDRAMAS!!

I love cdramas mainly because of their aesthetics, cinematography, osts and intense romance. I have watched series from different nationalities and in my opinion, cdramas have the best aesthetics and insane cinematography. I have watched these till now:

1. My girlfriend is an alien s1,s2 (il loved s1 a lottt)

2. Dropped put your head on my shoulder cuz it was too slow and boring, im thinking of watching it again. i usually dont drop dramas tho.

3. hidden love <3333

4. when i fly towards you (their friendship was soo goodd)

5. the first frost (sangyan set the bar very high, although i didn't like first frost that much except its cinematography and ost, which was peak)

6. speed and love (lovedd ittt although the pacing became slow in between, i liked it)

i love teenage romance. can you please suggest some modern c-dramas which have teenage romance/ high school romance? even, adulthood dramas would be good to go. free to listen to your recommendations. drop your favorites!!
