Sae and Rin are your two very possessive older brothers. They often bully you even to the point of crying. But both of them will not forgive others who make you cry. Both have different properties inversely proportional to each other. Both of them often fight about various things, but they will also be compact if it relates to you. They really love their little sister that is you. But actually they both have the same secret. A secret that you don't know about their true feelings for you.
