The reason this BL series is becoming famous worldwide it’s because we are tired of BL series with only focus on university lifestyle.. This indeed a very new kind of romantic between a soldier and a volunteer teacher which the scene are not in university but in some isolated place far from city. When they release the trailer a year back I really excited honestly to watched the whole series ASAP.. I hope all producer will produce more BL series that focus on reality of working lifestyle.. too many student lifestyle make me feel those series are boring unless the series are developing from student life to working life like sotus the series and how they maintain their relationship for a long time. As a fan of BL series, I hope they will producing more series like this in future but focus on other kind of occupation..
