These two are slice-of-life shows that center around a day-in-the-life of a group of high school boys. Both shows focuses on the interaction between the boys in the group and on the romances that each of them are involved with. All of the characters of both shows fall under a character trope but they are still fun to watch.

The Slapstick Comedy of these shows are pretty similar, both shows focus on a romance, albeit in a comedic fashion. Both shows have a variety of characters with different interests and personalities all coming together to make a group of friends.

Comedic aura. The side character has a crush on a girl. The MC is dense to the girl who actually likes him.

Shoujo from male character perspective. Setting is maybe not exactly the same, but feeling is pretty the same. Both series are really funny. Nijiiro Days is focused on more characters/couples, when Ore Monogatari!! is focused almost only on relationship of main couple..

Cute characters, same vibe and feel. Main couple - shy and embarassed, sometimes aloof and awkward. Natsuki and Kazehaya are similar characters chasing the girl, and opening her up in the process. Sawako and Anna slowly experiencing feelings they had never felt before and making more friends!

A tale of 4 friends on how they found their love interests through their school life and the story of their romance, friendship, experience and their everyday lives. (Genre: Slice of life, Romance, School.)

although these two anime may seem different right off the bat, its very similar in terms of romance. anna has a friend whos interested in her, and that hinders natsuki's progress in maintaining a relationship with anna. in tamako love story, mochizou likes tamako, but midori, the school president, also likes her to point of attraction, and that also hinders mochizou's progress in confessing to tamako. mochizous crush on tamako is as obvious as natsukis crush on anna. natsuki has a group of friends who'd help him get with anna; mochizou has a group of friends who know his crush on tamako, and theyll be willing to help him.

both series revolves around a group of boys with distinct character. Each male character represents a specific stereotype.
both series are cute, comedy and romantic.

Both are kinda short shoujo comedies with romance (not focused on just one couple) and good art. Boys have the most important part in these two animes.

Good romance, it has a group as the main focus and they are not clichés, but rather short both and contains light comedy as well.

Girl seems disinterest or to hate the guy. Guy is cheeky.

the refreshing vibe is similar. relationship after Anna realises her feelings for Natsuki reminds me of Futaba's emotions for Kou!
