Your spoiler is not really a spoiler. And that's the most sad part. We're just waiting for he Tian to leave and Jian Tinto disappear:(
stop reminding me
huuh what do you mean He Tain will leave??
If you read till now you gonna remember that the firsts chapters are about Jian coming back after disappearing in the high school.
About He Tian is "less official" because Old Xian revealed that he is going to leave China in the specials of Christmas. If you come back you will se that in these specials He Tian came back after staying on some other country for some time and then he goes meet Mo. The reason is not in the specials but in the current story, his brother and father apparently are trying to make him leave for a long time to study (sorry if it was confuse. English is not my first language)
Sorry mate were together in this were together.
This is the calm before the storm. Little Mo is gonna be devastated when He Tian leaves and there's nothing that can prepare me for that...
