ZLR & SZZ:
their first meet was only so cinematic, it was so beautifully depicted. ZZ falling in love at first is just so easily connectable to everyone who watches. ZLR being the most typical introvert, but not a cold ml, and slowly opening up to her was so excellently shown. it was the perfect representation of SHE FELL FIRST, BUT HE FELL HARDER. i also loved how the fl wasn't just chasing him, not also smart in her own strengths and helped the ml. she even helped his brother, and made her bond stronger. i really also liked how the ml always smiled at her and that way in the last ep, he gives a huge smile to her being pregnant . my pov: it felt like he wanted to bite her cheeks, lol XD. most importantly, they were not toxic at all, she told him that didn't need study in the same uni, and told him to chase his dreams while she chase her own. in conclusion, they were most cutest & perfect couple u could ever ask for.

GR & JJ:
this couple has special place in my heart. the way he fell for her, like really really hard, but still supported her, that was so heartwarming to watch. i love his efforts were made known to her, he fell first, becoz she was like star to him, too precious to approach, the way he notices every single detail of hers, he buys her a gift when that other guy didn't, he gets her pads even though it might be embarrassing for some guys, he was just too flawless, and the way she supports/encourages when she thought she had no dreams. JJ was such optimistic character, but her sadness was always noticed by GR. this couple was magnificent and splendid in their own ways.

FRIENDSHIP:
i love how all the 5 of them were always there for each other.
they helped ZZ when she was falsely accused by searching dustbins.
they helped GR, by staying by his side when he was sick and lonely.
they helped GF, by dealing with his trauma and being there when his grandma was sick.
and many more to go...

Last but not the least, you have to give his cdrama a watch.
I LOVED THIS CDRAMA. ❤️
