Genres: it is a comedy, romance, possibly shoujo. I believe it is still ongoing. I believe it was recently released, the recent chapter was updated in either May or June. Most likely June.

Synopsis: The main character is actually a guy. He coincidentally meets his younger sister's best friend on the way to work. He flirts with many people, but never took anyone seriously. Her frank, disgusted reaction to his flirting makes him fall in love with her immediately, much to the girl's horror.

In one chapter, He sends flowers. Her name means 'one flower'. In another chapter, when a ( girl ) friend of his interrupted his "date" with his crush, he took a napkin and rubbed her makeup. She exclaims he ruined her makeup and how her fake eyelashes fell, to which he responds by asking if she wanted him to rip the other ones off for interrupting his time with his crush.

If you can name this manga it would be so helpful! I would really like to read it but I completely forgot the title, author, character names.....
Thank you!

I found it, lol, it is called Koi to Yobu in wa Kimochi Warui if you are interested! Funny and cute. It is actually a Josei
