I hope I wrote something understandable because I’m not really good with English (≧∀≦)
Personally, in his same situation, I always ask my friends what I can do, because I am shy and inexperienced (even if I am 21). So I don't blame him, because everything he did was really cute!
But it’s okay, this is only my thought (⌒▽⌒)
He accepted her help because he hasn’t friends, he got what he could... and what’s bad about cheering for him, giving him drinks and roses? These are really cute things! And the scene, where he’s reading yaoi, was to give us a laugh. And it underlines his inexperience! And don’t get me wrong, I know yaoi aren’t a good example to be followed
Speaking about yaoi, why is everyone complaining Lihaun and not all that raper in lot of yaoi?? Lihaun is kind, sweet and he’s not hurting Yuyang in any way!!
For everyone who is saying that Lihaun is too clingy I want to say something:
1. If someone tells you that you don’t like them even if you confessed to them, would you really accept it? Or would you try to prove your love?
2. Taking in consideration what I wrote before, Lihaun is only inexpert, so to prove his love is doing childish things because he doesn’t know what to do! You have to remember that he has problems to approach people, so he’s doing childish things because he has a pure heart
3. Yuyang is the childish one to be honest, because he doesn’t believe that Lihaun has feelings for him and he said he like someone else without thinking about what Lihaun could feel
4. I don’t see anything wrong to prove your love to someone. Lihaun isn’t doing anything that could hurt Yuyang, he’s only trying and trying to prove his love and you don’t have confusing it with obsession because that’s totally love
