Of the three, Obsessed is what gave it the higher score, as on its own I'd give it a 9. Fair warning the characters are a little toxic but the story and acting were incredible. I really fell in love with Teddy Ren and was so sad to see he didn't do anything else after this.
All three had interesting and unique stories and I'm glad I watched them, Taiwanese BLs just hit different for me.
There were a few familiar faces, particularly the guy from Beloved In House: I Do I liked his role in the first installment although until the ending I did think it was going to disappoint me.. it didn't.
For being 7 years old I think they aged well and recommend them.
