The first small coup, make a small change in appearance. Straight men generally can't tell whether a girl has makeup or not, and always think that putting on big red lips is heavy makeup, so we can seize the "loophole" between plain makeup and light makeup, and it is naturally important to have a clear sense of makeup. Don't think too much about whether to wear it or not. A little caution is enough, such as wearing fairy-tale skirts, T-shirts and shorts, and sneakers. This kind of girl's collocation is very attractive to them.
The second small coup, take the initiative to establish contact between you. Although straight men don't care about details most of the time, they are also easily unconsciously "routine". For example, wink and smile at him, ask him some small questions and ask him to fix your computer and light bulb. And actively looking for opportunities to get in touch with him will not only make him feel good about you, but also give him the feeling of being needed all the time and unconsciously feel good about you.
The third measure is to find the right time to express love. After layers of preparation, when you get used to each other, you suddenly leave and come to him unexpectedly. For example, if you don't talk to him for a few days, he may be tempted to ask how you are recently, which shows that he already cares about you. At this time, you just need to find a good way to express your love. When chatting with him at dinner, you can casually talk about your relationship problems, such as "we chat every day and colleagues think you are my boyfriend." Ha ha ha ha "these jokes are also very euphemistic. Maybe you can point to him and confess to you.
All in all, straight men just don't care so much about details, but they are also people with feelings, and they can't hide their love!
