100%!!
i’ll just ask for clarifications though, because i’m under the impression that jian yi and he tian left together (during their long hiatus let’s call it) because he tian’s brother (or his family rather) is kind of involved with jian yi’s father so they were kind of responsible for jian yi? does that mean that jian yi got back earlier than he tian, who only got back during christmas?
That I can't say. As of right now all we know is that He Cheng wants He tian to switch schools? Which is probably for his safety but also to probably get him into the family business more as we know he does as an adult. Jian Yi kinda just gets whisked away to the middle of nowhere (more so for his safety). As to if they both disappeared at the same time and if there's a connection there, Old Xian will have to connect the dots for us on that.
thank you!
For everyone confused about the time skip with adult He Tian and Momo, I think the author has insinuated that He Tian comes and goes for long periods away from Momo (i.e the past christmas chapter when Momo was working at the restaurant; now working at a car shop etc), probably due to his brothers/family business . Momo doesn't seem to ever know how long he'd be gone for or for what. He Tian just leaves and pops back up when he can to see Momo. Momo is grumpy because he misses him and it obviously hurts to see He Tian there one minute then disappear for who knows how long. All he can do is wait for him.
As for Jian Yi and Xixi, it looks like the most recent update seems to be a bit after their reunion as adults as well, and getting back into the familiarity and the continuity of their relationship. Hence why Jian Yi commented on how Xixi's sister has grown.
