Be Loved in House: I Do

Be Loved in House: I do and We Best Love: Fighting Mr. 2nd are both dramas which belong to the same genre: Boys Love. Also, both dramas are made and the stories are set in Taiwan.

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.
