Be Loved in House: I Do

Both dramas are office Romance.
In history 4, ting ting falls in love with his friend and both of them fear love kinda like the ml in be loved.

I don't know but I can for certain say that if you like the one, you'll love the other. I watched History 4 before Be loved so I can say with ease that both are unique in their own way.

Both BL series have an office setting, funny moments, hot actors in leading roles, above-the-average quality and are light-hearted and heart-warming. The only big difference is that Cherry Magic has the "secret crush" trope while Be Loved in House: I Do has the "enemies-to-lovers" trope.

Be Loved in House Special, as it is clear in its own name, is a Special of Be Loved in House: I Do which is the official drama, so it is fair that it is related to the other one.

Both BL dramas are based on the "enemies-to-lovers" trope, the main characters work together (although at least one of them initially doesn't enjoy it at all), both the series are funny and light-hearted and have very attractive actors in leading roles.
