1. Many guys who do not smoke, drink, or play video games often struggle with their social skills. They tend to focus on their studies and have introverted personalities, which makes them less likely to actively engage with the opposite sex. Their reserved nature may give them an unattractive edge, as they rarely take the initiative to approach potential romantic interests.2. Girls are easily swayed by superficial factors when it comes to dating. Due to their lack of life experience, they are attracted to guys who can provide them with a sense of being treated like princesses. Boys who smoke, drink, and play video games are often more skilled in social settings, particularly when it comes to understanding and catering to the needs of girls. Despite their academic shortcomings, their high emotional intelligence allows them to easily discern what girls want, leading to a romantic pursuit that fulfills the girls' desire for attention and pampering. At this stage, girls are typically seeking romance and enjoy being adored, often without giving much thought to the true purpose of seeking a boyfriend. It's only later that they realize the problem, but it may already be too late.In summary, the lack of a girlfriend among guys who do not smoke, drink, or play video games can be attributed to two main reasons: their poor social skills and the tendency of girls to be swayed by superficial factors when choosing a partner. This combination results in their inability to secure a girlfriend.
