Race to Romance

Both are sports themed dramas in which the FL disguises herself as a girl to join a team and ends up sharing a room with the ML.

Both are short length dramas centered around the leads being race car drivers.
............................................................................

Both FLs disguise themselves as their brothers and enter a male-only place in order to fulfil their loved one's dream. Both are mini dramas.

The K-drama and the mini-drama have almost the same plot.
- FL impersonate her twin brother who is in the hospital.
- FL meets ML for the first time and they dislike each other.
- SML (Kang Shin Woo) and SML (Fang Chi)'s character development are very similar IYKYK.

female disguised as male in both shows for having a similar situation only having males recruited around her

male is having a close relationship to female, believing she is male all the way till doubting about her real gender when noticing that she is not having masculine features

both includes love triangle with second male lead discovering the hidden identity of female before first male lead knowing about her

female is blamed to not revealing her gender and acting selfishly when making male confused about her and feeling that the attraction feelings he is having towards her couldn't be for a male

Both FLs disguise as boys in order to take the place who their brother who is dead or injured and fulfill his dream. Both end up sharing a room with the ML.

What I find similar to SPEED AND LOVE is that the romance is sweet and complex, and it's set in the world of motor racing, but this time at a truly professional level. The female lead, however, is the complete opposite of feminine, but the romance is intense!
