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.
We Best Love: No. 1 For You is a Taiwanese drama included in the BL genre and in the dramas with the tag LGBTQ+, this way, people who watched Loved in House Special can also like that one.
