Shen Ci told himself to listen to Meng Chuyue in everything.
He had indeed always demanded that of himself.
However, he progressively moved from being slightly unhappy to very unhappy.
As for suspecting that Meng Chuyue didn't love him?
He did not.
Meng Chuyue had always treated him well, even revealing the secret of "space" to him. How could she do that if she didn't love him?
Yet, he found Meng Chuyue's decision to postpone their wedding for nearly a year due to "superstitious beliefs" somewhat irrational.
He couldn't bring himself to resent her, but felt a void of desolation inside.
If Meng Chuyue had continued to treat him as before, he might have felt slightly better.
