There are no similarities plot wise, but if you are looking for another BL where the characters play sports, in this case volleyball, then Crossing the Line is an obvious suggestion.

When she is told that demons and gods can never be, she takes his advice to heart to cultivate and achieve immortality. Upon her ascension, Hong Ning learns that Jin Xiu is marrying someone else. She resolutely abandons an immortal life to enter the cycle of reincarnation, simply to forget him. Jin Xiu defies fate itself in order for Hong Ning to be reborn. He hopes to repay his debts and protect her for a lifetime. A misunderstanding that cannot be avoided, an identity for which there is no escape; when spring ends, the two meet again. Hong Ning is destined to become Jin Xiu's trial in love.

In Come and Hug, the ML protected FL. ML went on to become a police officer in order to protect FL from his psychopathic father, while in Castaway Diva, ML indirectly watches out for FL by involving himself in every situation FL is in.

FL in come and hug and FL of castaway diva are talented people, one is an actress while the other is an aspiring singer.

Come and hug me is a rather dark show compared to Castaway Diva (there's murder)

If u like republic spy drama or spy dramas in general then both drama are worthy watches. A cleaver protagonist and powerful antagonists with twists and turns.

More mature storytelling & line. Intelligent females handcuffed by ruthless & fearless love who are able to break through and live life terms more to their favor.

Male and female before even meeting in real life.. Liked each other... And once met... Came into relationship very very soon... And no breakup or unnecessary misunderstanding...
Male loves female only and female loves male only

Though both the dramas have parallel universe sci-fi shit, Train shows more of a thriller showcase than Derailment while the latter shows more romance.
Even the titles are interlinked.
In Derailment, we see the FL trying to find herself but in Train we see ML trying to find a serial killer. Train has a very subtle romance and isnt the main genre.
But both are very captivating.
