Oh Riku loves to be loved, he’s an absolute puppy for some affection. Any token of affection or appreciation gets you a long ways with this one. He treasures those he loves very deeply, even if he becomes at odds with them. A perfect example being his relationship with his elder brother Tomoe. While the two are in an estranged relationship now, and hardly speak Riku still loves his brother fiercely. If Tomoe was ever physical hurt Riku would be worried and upset about it. He feels the emotional pain of others very easily, and when he loves it becomes even more intense.
Unfortunately though, Riku doesn’t come without his problems with love. He’s horribly inexperienced with anything beyond puppy love and childhood crushes. He may know a thing or two about kissing, but when it comes to actually being in love, or a romantic relationship--hell even dates, Riku is horribly awkward and nervous. He wants everything to go perfectly and for the person he’s with to have the time of their lives--even if it means a bit of self sacrifice. This can however cause plenty of problems, especially when coupled with Riku’s poor ability to communicate what he’s feeling--preferring to bury it under a thousand questions. He’ll shower his lover in every material form of expression of love under the sun but actually saying the words ‘I love you’ is quite the challenge.
♫ - headcanon about music
Riku loves music about as much as the next average guy. He’s not overly musical... or musical at all as far as talent is concerned. He finds Karaoke to be entertaining for the purpose of something to do, but he’s not wildly addicted or anything. Listening to CDs is about the same level of interest. It’s a fun activity and he likes hearing new music, but he doesn’t make much interest in actually seeking things out. Generally he listens to whatever is playing without much complaint. His preferences would be more towards modern pop and rock music--something easily recognized on the radio. Other styles like classical or rap he tolerates but he’s not crazy about it. Since his parents own a shop however, he’s become quite used to classical as background noise.
✓ - headcanon about friends
Riku is definitely one of those people that has hundreds of casual friends. He’s a very friendly and social person and is quick to make friends with anyone he talks to--even if the other person may not be so friendly. He’s genuinely honest (sometimes a bit too much) and wears his heart on his sleeve. So even when he tries to lie it’s typically no good.
Once you’re on the friend committee you’re automatically enrolled into the trust committee and the hang out committee. Basically, if Riku’s talked to you, liked you most likely your phone numbers will be exchanged, and you’ll be called up to hang out sometimes. Riku will put all of his trust into you that you won’t hurt him, but at the same time you won’t ever really know all of Riku. He guards the things he truly cares about very deep inside, and while the sight of them is visible the details are not.
Don’t feel bad though, you’ve still got a peppy ray of sunshine by your side that will always be there to pick you up and look for a good time. It could be said though... that perhaps the reason Riku is so eager to make many friends is to make up for another close relation that has been deeply damaged, and try as he might to fill the void it’s just never enough to replace or heal this one.
