In both drama you are bound to cry your eyes out watching the love stories develop. Through thick and thin, through various hardships and struggles you see a beautiful yet heartbreaking and flawed romance. The difference of the two drama lies on the choices of our main characters and how they deal with the terminal illness.

Childhood friends-to lovers with the ml falling first for the fl. Bickering, misunderstandings and living close to each other tropes.

Both are webtoon adaptations.
Vampires and a interspecies romance with some potential but things didnt exactly worked out.

Both drama have gender bender romance with excellent casting choices for the fls. In both drama the fl had to hide her gender in order to survive(well not so much in one case but superstition is a peculiar thing) and becomes an aide to the ml. Bickering and falling in love kind of dramas

Both drama focus on editors and what their job entails. The romance in both drama isn't the main story, it is a part of it.

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.
