Meaning of “ReaKo(リアコ)”
“ReaKo(リアコ)” is an abstraction for “Real(リアル) Ni(に) Koishiteru(恋してる)” which means “being in love with own Oshi(推し)” (and this oshi(推し) is unreachable because they are anime character or idol or so).
Koishiteru(恋してる) means being in love.
It’s real love, so sometimes they get jealous of rivals who have same oshi(推し).
In Japan, many young people have oshi(推し). That’s why “ReaKo(リアコ)” is not so uncommon.

Almost same, but in my image, “リアコ” use for female only.
I imagine “リアコ” people are girls.
