I've just finished "In Love Forever" and here are my thoughts.
This drama started very strongly in my opinion. There was a fun dynamic between the leads (Ran and Neen), and I really liked the fact that I was finally watching a main character (Nene) in a GL drama stand up to the psycho mother in law who was persecuting her. However, the relentless persecution of Neen by her mother in law basically became the driving plot of whole drama and I will confess it got a bit much after a while, with too much screaming and hateful "I want to kill you" stares . This also caused the drama to take on a darker vibe in its second half. I also think the resolution with Ran's psycho mother at the end of the drama could have been better. Trimming the entire series by a couple of episodes probably would have helped.
I thought Orm's acting was excellent, especially her emotional scenes. Ling Ling had an easier job, as her character never lost control of her emotions . Consequently, her acting didn't stand out to me.
Even with its faults, I did enjoy this drama and I definitely think it is better than the current MDL of 7.3 would indicate. Definitely a "recommended" for any GL drama fans.
