The Age Gaps were treated differently in other works of CLAMP aside from CCS

The Age Gap relationships were treated differently in other works of CLAMP aside from CCS, are that the age gap couples WAIT for a time when it is possible to be with each other the Suki couple, Hikaru/Lantis, and Nekoi/Kusanagi are examples of that.

Suu and Kazuhiko are not a couple but rather Kazuhiko is still in love with Oruha.

Seishirou/Subaru is not even portrayed as a healthy couple.
