When a guy says "roses are in bloom", he may be implying that he has a crush on you, which means that the roses have reached the stage of blooming, beautiful and fragrant. On the other hand, it can also be a metaphor that certain emotions or relationships have matured to a critical moment.
You can reply depending on the level of your relationship and how you feel:
1.If you have feelings for him and are willing to accept his confession, you can reply:"That's so nice and I look forward to enjoying the beautiful flowers with you。Show that you also have feelings for him and are willing to go through the growth of this relationship with him.
2.If you don't have feelings for him or aren't sure yet, you can reply:"Roses are indeed beautiful, but I prefer lilies and we need time to get to know each other as well。It expresses your attitude and also gives him a certain amount of space to further develop your relationship.
3.If you want to keep your distance, but don't want to be too aloof, you can reply: "Mei."The roses are indeed beautiful, but I also have a lot of other things to focus on. "Show that you have your own life and purpose.
Whichever way you choose to respond, be mindful of expressing your true feelings and attitudes. Remember, honesty and directness are the best ways to communicate.
If you're not sure what the other person means, you can ask him directly. If you are not interested in his feelings, tell him clearly as well, so that misunderstandings and unnecessary harm can be avoided.
I hope that one day, everyone can meet a romantic confession, and the roses will bloom, just like my love for you, and they will bloom naturally.
