The uni arc is similar... Minus the toxic of course.
If Cheese In The Trap had decided to tone it down and not go down the way it did, the result would be the uni arc of Forever Love.

both drama have a sweet and a bit angsty romance. Fighting for their love while growing together. Hard work and societal injustice are also very present themes in both drama.

In both drama healing and finding someone to be yourself and improve as a person through that relationship is important. Work environment/office romance is also there in both. There are also many similarities between the main characters and of course the side romance.

Both drama are sweet love stories about finding someone that understands and accepts you as you are. Both are comforting and healing drama.

Both drama have:
Relationships that blossom from random meetings, fashion, the theme of stepping out of your bubble and comfort zone and finding fun in places you didnt expect.

Falling in love after 30? with a partner younger than you??? Such a "scandal"
Both drama are about a blooming romance between a couple with an age difference, the societal expectations of how one's life should be at a certain point in life and how one deals with it in order to be with the one they like. In both drama, you could say there is some type of office romance and there is a strong presence of secondary couples and storylines. Though one has to admit that Find Yourself was by far the more frustrating of the two in terms of the fls' insecurities and troubles surrounding their dating life and love in general.

In both drama we have a strong seemingly cold hearted but actually a softie fl falls in love with a soft ml who just gives in to (almost) every one of the fls wishes. While in Begin Again we have some twists and turns Love is Science is a more relaxing journey of falling in love. Cute secondary couples with a strong presence in the storyline and their fair share of screentime.

Same with the 2003 version: The main similarity is the on/off mode of our main character and their need to hide their insecurities and personality traits they think that contrast their "perfect" image(if you ask me everyone shows a different face depending on where they are anyway) . Another similarity is the sweet/demanding persona of the mls. Also older woman/younger man trope happens in both.

Both drama are about a "perfect" capable career woman who just wants to sit back, relax and be a total mess inside her own house(gym clothes+beer+manga= happiness). Romance that makes our heroines both become comfortable with showing their true self and slowly make some space in their life for the male lead. Some up and downs but basically both are short, fun and sweet drama with a dose of ridiculous moments of course.

From the synopsis alone one can see that there will be some similarities between the two drama like it is a North-South Korean romance,the fl is a soldier and the ml is famous
Will update this when it airs though

Both drama are about a contract relationship that blooms into love and understanding. Opposites attract and life-doesnt-go-the-way-you-want-it are themes that appear in both drama.
Though BTIMFL is more of a slow paced and mature slice of life and Begin Again is more active and playful rom com, both drama couples had an amazing flow. Both drama could easily become off putting due to the plot itself but the actors in both cases did a really good job delivering their roles. You might not understand or agree with the mcs' choices so keep that in mind.
