What makes this drama so special? For me personally, it was the lack of cliches. Our female lead can stand her ground, she isn't a damsel in distress who needs saving every time. She also knows what she wants. Our male lead, although younger he has proven just how mature he can be and how much he cares for her. As he said, "she can worry about beauty, I'll worry about her health". They are both willing to comprise.

When an issue presented itself instead of breaking up they dealt with it. I've seen many dramas that when an issue arises the first thought is always to break up because they think that's what's best for the other person. Like Lin Yang said, "I won't hurt him and I won't hurt myself". This drama presented a realistic view of a relationship.

They are childhood friends, she has seen him since he was a baby. He fell in love with her when he was 15, and saw her go through many breakups yet he never gave up. He knew what he wanted and he charged forwards for it. He never hesitated in showing his love for her.

Love triangle? yes but it's so light that you barely feel it's there and it got resolved halfway through the drama.
Annoying second female lead? yes, but he always made it clear and drew a bright red line between them which left no room for misunderstandings. Our female lead also stood her ground. Although annoying li tian came around.

Supportive parents? Yes, it would be weird if they didn't support them considering they wanted their kids to marry even before they were conceived. Plus they treated each other's children as their own.

Supportive bestfriends? Yes, there is no backstabbing. They felt like that ride-or-die type of friend.

I would recommend this drama. It's light but it still manages to portray a good relationship between the leads.
