The summary don't make sense, is the romance between siblings?!...... BaeSuzy
Yes, bout a brother and sister who suddenly have they're bodies switch (along with other classmates) and they have figure how to get back to normal along with dealing understanding their true feelings. Tho tbh it probably been better without the body swap for a better story
Change back to their proper bodies, it's a interesting story but it isn't that great tbh
