Sugar*Soldier

Both anime are short episodes - 1 minute each! Don't expect too much, I personally think they're both made to get you curious for the manga. 

Nagareboshi Lens and Sugar Soldier have a shy girl/outcast as protagonist who falls in love with a popular outgoing guy who is very sweet and kind to her. Also, both have lovely artwork.  

There're both anime with just three really short episodes. Both seem to be more like an advertisement for the manga, since they're more like previews with really shorts moments. They spoil a bit of the moments, but also make me want to read the manga. They look like a typical shoujo romance anime/manga, but still give you that fangirl feeling (if you're into cute romance anime [and/or manga]). The art is similar, even though Sugar Soldier looks a little better in my opinion. 

Since she was a child, Makoto was always compared to her beautiful sister. But she decided to become as awesome as she is for her entrance in High school. but it didn't really work... And then, she met a guy who's popular and older than her?! Makoto can't stop her heart to beat so fast. And then, she can't stop thinking about her school life! 

In both story's main character have a sister whose work as an model. Akari and Makoto are jealous of their sister because their sister Monica/Rika is very pretty instead Akari and Makoto are cute but not cute like their sister. The main character of the anime/manga thought their mother prefer their sister because their mother spend more time with her sister（Jewelpet tinkle) and their mother take more picture of their sister ( Sugar soldier). At last, of course in both story their sister care about the main character as well as their mother. Extra: Both story have a main character who like a popular guy and like him a lot because of their own reason and is a very cute romance story. (In this anime is short, so mostly I'm telling from the Sugar solder manga point of view)  read more 

Both are very short anime specials made to promote their manga. The artwork is very pretty in both of them. They are both romance stories and from the point of view of the female lead! If you only have a couple of minutes time, want to watch something quick and get a small insight of some shoujo manga these are pretty much perfect for you! and I'm sure if you liked one you'll like the other as well :) 

-Both are cute and romantic -Both typical cute shoujo animes -Both main guy character is a very fun guy and everyone likes him. He likes the main girl character and doesn't care much about appearances.  

Both are very cute, romantic, typical shoujo anime and are about the guy who doesn't care much about appearances and cares more about personality. Both anime give off the same vib.
