Ryouta has strong feelings for Rose and continuously showers her with affection until she gets the point. He admires how strong she is and how she'll stand up for her friends.
Ryouta couldn't give a damn about Saphira, she's not his kind of person and he hates how she blames him for any wrong that might happen throughout each day.
Although Ryouta likes Jesse's company he has a strong dislike for him as he shares Rose's affection with him which he can't stand doing. He also hates how cheeful he always is.
