100% compatibility!? No way I'm believing that!
About
The year is 20XX. To combat the declining birthrate and aging population, the government has established the Matching Partner System for all 16-year-olds nationwide. Participants with a compatibility rating of 80% or higher are obligated to date that partner for six months. While marriage rates have risen, opinions on revising the system exist because couples can break up after the six-month period, and occasionally, same-sex compatibility is found to be exceptionally high. ────────────────────── 【Relationship between Ren and Guest】
