This kind of 青梅竹马 relationship is likely to run into problems later on when they're in their 30s when a third party appears. The guy especially. I have seen so many cases already. So far there's only one couple I know who are still together since sec 2. And you know why? The wife secretly told me that the husband is impotent. They have no children. I suspect that the wife had some ONS outside during her younger days as she was a party animal even when she was in her 30s. The husband is quite nerdy. Looks a little like Gan Kim Yong.
