Excellent drama about a love story between an older woman and a younger man. Good acting by leads, healthy relationship.

Both of these dramas center around a female lead who is in a 5-year marriage that has lacked intimacy for several years leading to a sense of unfulfillment and a venture into infidelity from at least one of the married individuals.

Both have similar vibes.

In both of them,main female leads are topper.

love triangle is there.

A teen 2 is a very nice and short webseries and please classmate is longer in duration.
I would strongly suggest to watch both of them

I just like couple centred shows. This one is slow and couple centred. Although FE has outside angst but ML/FL never wavered.

- ML falls in love at first sight;
- ML strives to become more successful because of FL;
- smart FL;
- smart ML;
- some actors playing secondary characters are in both dramas;
- comedic moments

One is a movie and the other one is a drama.
Both are about past lovers who meet each other again when they become adults.
The ML in both is Jing Bo Ran.
The leads in both have great chemistry.
Road home is a feel-good romantic drama, yet Us and Them is a bit darker and shows the different paths the young lovers choose.

- smart FL;
- smart ML;
- similar vibe and costumes;
- ML is a government official;
- interesting supporting characters

Both are about childhood friends turned lovers
Dramas have feel-good vibes and the leads have great chemistry.
Soundtrack #1 shows an unrequited love that blossoms when the leads are adults, yet road home both leads fall in love with each other since their school days

Both drama is similar in terms of sports. Which focus on the story how lead actor growth (losing and finding the passion, facing and overcome their difficulties, romance with female lead and helped the male lead to overcome and assisted in their difficulties).
