Art and Sound are the same, with probably the catchiest song out of all of theme song out of all of them..
Now for the parts that make this so infamous
This has the most story ,but it's not well written. The main conflict is the titular "love" triangle and the climax is CoCo running away only for them to make up and ending with the infamous threesome in Tokyo Tower. While it's not as bad as Pico instantly forgiving Tamotsu for treating him like a sex object, it's still jarring. I'm glad this has the most part ,but there's still cringeworthy Shotacon smut.
The characthers are pretty bland with the possible exception of Chico due to acting like a real boy. Although CoCo's rather fascinating even if he/she is too similiar to Pico just add more Crossdressing. Although here's something Id like to discuss in the threads: Is CoCo transgendered? Think about it, aside from one scene in the opening where he/she is wearing a gakuran, he's almost exclusively seen in girls clothing. I go into more detail in my hate fic sequel, but it's a subject that buzzed in my mind for a while.
Enjoyment? Obviously I am not a Shotacon, so I did not enjoy the sex scenes. And trust me there are a lot of them.
Overall I give this a 3/10. Not as bad as the other OVAs ,but still pretty bad.
