Grey Rainbow is the best Asian bl series I've ever watched for now but I'm sad because it is under-rated, may be they lacks media exposure or advertising or promoting of their series. Generally, series like 2moons or so many thai series only include romantic or fan service scenes and they don't usually displays anything outside of the campus like family life etc. and I feel like everyday for them is like disney happy ending and just playing around, flirting and may be this kind of entertainment is sometimes kinda boring because of lacking substance and originality (I agree it is sweet for the first time but 2nd time, may be boring tho) and rewatched value is 1/10. I think handsomeness and cuteness alone can't make a great series. I even thought that it was almost impossible to find a masterpiece from Thai before watching this series. I'm glad that this series differs from those over-rated series. It is touched, meaningful and deep. It depicts religious views, difficulties of a gay's life and their thoughts, and other things that makes it everything on point. The music is great. I like both original sound tracks "Ray of Love" and "Pause". It reflects the series. I am very confident that if you like this kind of drama, you would not be boring to watch it again but instead, your love toward this will grow more and more. (I'm not exagerating) I still can't move on from this series. It's been already 1week. It's truly a gem.
